Re-worked Liberation job: it is now a more quicker intel-esque job that will only reveal liberation missions.

Added additional checks at various points of the job process, this should stop liberation missions from spawning like weeds unintentionally.

Added safety check so job won't spawn liberation missions all around the world, instead of just in the region.

Fixed logic error preventing just contacted regions from spawning Liberation stage 1 missions.

Made it so the more strenuous checks will only proc in regions that actually need them.

Job should no longer proc once the Tower network mission is available. It will also halt progress if you have an already existing stage 3 liberation mission on the geoscape.

Added localization support for robojumper's better job selector

NOW it should give you the 3rd stage liberation mission when appropriate.

Should now give you the 3rd liberation job when appropriate.

Fixed crashing issue.
