Fix #117: Replace language string joins

Re-licensed the project under the MIT license

Fix #101: Allow importing of all repos via id=all ...

Reworked import processing to allow passing id=all to the GET query
instead of a numeric Repo ID.  With this argument, the system will
automatically run the "import latest" for all repositories configured
for source integration.  This will simplify the process for keeping a
large number of repositories up to date via cron job.

Cleaned out output from repository import to look nicer, and support an
eventual UI option to import latest from all repos.

Issue #90: Move to direct-call framework design ...

Rather than signalling events everywhere and letting extension plugins
handle them if they choose to, the framework should be reworked to
directly call functions on the appropriate integration plugin. This will
both reduce overhead from events and simplify plugin work by removing if
statements at the beginning of every event handler.

This will require follow-on changes to all source integration plugins to
work with the new parent class API.

Version bump in Source plugin to signify API changes.
