removed most custom add_*data* wrappers from Main.c
removed makeCurrent() from Text.c (was never in a release), use "bpy.texts.active = text" now
clamp new image sizes
made add_empty_action accept a string rather then a blocktype since the blocktype was only being used to choose one of 3 strings anyway.
