* Added a flag that tells anvil-daemon when a node is having it's network mapped. When this happens, open ssh connections are closed each loop and only tasks related to mapping the network run. This improves responsiveness in Striker when reporting which network links have come up or gone down.

* Fixed a bug in Database->insert_or_update_variables() where, if 'update_value_only' was set but not variable_uuid was passed or could be found, an (incomplete) INSERT would be attempted.
* Added support for generating module metadata when setting up local repos on Striker.
