Created Database->get_variables().

Browse Source 
* Updated (NOT COMPLETE!) System->check_if_configured to take the new
  'thorough' parameter to see if the network is no longer configured.
  When used, the method attempts to detect if a host has been
  rebuilt and, thus, no longer configured.
* Started work on having 'anvil-join-anvil --rejoin' try to see if the
  network needs to be reconfigured prior to rejoining the cluster.

=head2 get_variables
This method loads the C<< variables >> table data into memory.
If the record does NOT have a C<< variable_source_table >>, the data will be stored in the hash;
* variables::variable_uuid::<variable_uuid::global::variable_name = <variable_name>
* variables::variable_uuid::<variable_uuid::global::variable_value = <variable_value>
* variables::variable_uuid::<variable_uuid::global::variable_default = <variable_default>
* variables::variable_uuid::<variable_uuid::global::variable_description = <variable_description> (this is a string key)
* variables::variable_uuid::<variable_uuid::global::modified_date = <modified_date> (this is a plain text english date and time)
* variables::variable_uuid::<variable_uuid::global::modified_date_unix = <modified_date_unix> (this is the unix time stamp)
If there is a source table, then the data is stored in the hash;
* variables::variable_uuid::<variable_uuid::source_table::<source_table>::source_uuid::<source_uuid>::variable_name = <variable_name>
* variables::variable_uuid::<variable_uuid::source_table::<source_table>::source_uuid::<source_uuid>::variable_value = <variable_value>
* variables::variable_uuid::<variable_uuid::source_table::<source_table>::source_uuid::<source_uuid>::variable_default = <variable_default>

* variables::variable_uuid::<variable_uuid::source_table::<source_table>::source_uuid::<source_uuid>::modified_date_unix = <modified_date_unix> (this is the unix time stamp)
