Fixes for BMO_error_raise extraction regex, and add hindi to "active" translations.
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. :/
