Digimer 94d8a9c495 * Fixed a bug where finished jobs with a '0' picked-up time would be written to jobs.json. 
* Updated anvil-configure-striker to use Job methods and reboot using anvil-manage-power. Also updated it to set/clear maintenance mode and mark a reboot required at the end of it's run just prior to reboot.
* Lots of log cleanup.

=head1 NAME
Anvil::Tools
Provides a common oject handle to all Anvil::Tools::* module methods and handles invocation configuration.
=head1 SYNOPSIS
use Anvil::Tools;
# Get a common object handle on all Anvil::Tools::* modules.
my $anvil = Anvil::Tools->new();
# Again, but this time sets some initial values in the '$anvil->data' hash.
my $anvil = Anvil::Tools->new(
{
data => {
foo => "",
bar => [],
baz => {},
},
});
# This example gets the handle and also sets the default user and log
# languages as Japanese, sets a custom log file and sets the log level to
# '2'.
my $anvil = Anvil::Tools->new(
{
'Log' => {
user_language => "jp",
log_language => "jp"
level => 2,
},
});
=head1 DESCRIPTION
The Anvil::Tools module and all sub-modules are designed for use by Alteeve-based applications. It can be used as a general framework by anyone interested.
Core features are;
* Supports per user, per logging language selection where translations from from XML-formatted "String" files that support UTF8 and variable substitutions.
* Support for command-line and HTML output. Skinning support for HTML-based user interfaces.
* Redundant database access, resynchronization and archiving.
* Highly-native with minimal use of external perl modules and compiled code.

# Public methods #
#############################################################################################################
=head2 data
This is the method used to access the main hash reference that all user-accessible values are stored in. This includes words, configuration file variables and so forth.
When called without an argument, it returns the existing '$anvil->data' hash reference.
my $anvil = $anvil->data();
When called with a hash reference as the argument, it sets '$anvil->data' to the new hash.
my $some_hash = {};
my $anvil = $anvil->data($some_hash);
Data can be entered into or access by treating '$anvil->data' as a normal hash reference.
my $anvil = Anvil::Tools->new(
{
data => {
foo => "",
bar => [6, 4, 12],
baz => {
animal => "Cat",
thing => "Boat",
},
},
});
# Copy the 'Cat' value into the $animal variable.
my $animal = $anvil->data->{baz}{animal};
# Set 'A thing' in 'foo'.
$anvil->data->{foo} = "A thing";
The C<< $anvil >> variable is set inside all modules and acts as shared storage for variables, values and references in all modules. It acts as the core storage for most applications using Anvil::Tools.
=cut
sub data
{
my ($anvil) = shift;
# Pick up the passed in hash, if any.
$anvil->{DATA} = shift if $_[0];
return ($anvil->{DATA});
}
=head2 environment
This is the method used to check or set whether the program is outputting to command line or a browser.
When called without an argument, it returns the current environment.
if ($anvil->environment() eq "cli")
{
# format for STDOUT
}
elsif ($anvil->environment() eq "html")
{
# Use the template system to output HTML
}
When called with a string as the argument, that string will be set as the environment string.
$anvil->environment("cli");
Technically, any string can be used, however only 'cli' or 'html' are used by convention.
=cut
sub environment
{
my ($anvil) = shift;
weaken($anvil);
# Pick up the passed in delimiter, if any.

}
}
return ($anvil->data->{ENV_VALUES}{ENVIRONMENT});
}
=head2 nice_exit
This is a simple method to exit cleanly, closing database connections and exiting with the set exit code.
Parameters;
=head3 exit_code (optional)
If set, this will be the exit code. The default is to exit with code C<< 0 >>.

#############################################################################################################
# Private methods #
#############################################################################################################
=head2 _add_hash_reference
This is a helper to the '$anvil->_make_hash_reference' method. It is called each time a new string is to be created as a new hash key in the passed hash reference.
NOTE: Contributed by Shaun Fryer and Viktor Pavlenko by way of Toronto Perl Mongers.

}
=head2 _get_hash_reference
This is called when we need to parse a double-colon separated string into two or more elements which represent keys in the 'C<< $anvil->data >>' hash. Once suitably split up, the value is read and returned.
For example;
$anvil->data->{foo}{bar} = "baz";
my $value = $anvil->_get_hash_reference({ key => "foo::bar" });
The 'C<< $value >>' now contains "C<< baz >>".
NOTE: If the key is not found, 'C<< undef >>' is returned.
Parameters;
=head3 key (required)
This is the key to return the value for. If it is not passed, or if it does not have 'C<< :: >>' in it, 'C<< undef >>' will be returned.

}
$value = $current_hash_ref->{$last_key};
}

=head2 _make_hash_reference
This takes a string with double-colon seperators and divides on those double-colons to create a hash reference where each element is a hash key.
