Also enhanced the ugly py ast parsing code, so that it now can handle (up to some extent) "name" function nodes, and add bpy.app.translations.pgettext func familly to extracted ones...
This ast py parsing becomes more and more ugly, should probably try to refactor it a bit. :/
Notes:
* Most tools here have been updated, only a few (unused :p ) features should be missing. But some updates are rough for now, and performances are globally worse currently, will address this later (this is only really noticeable when you work over the whole repo, anyway ;) ).
* This update breaks "edit translations" addon, will fix it later, once core (i.e. this module) is considered stable again!
