* app/gegl/gimpoperation*.c: Prefix the GIMP GEGL operations with
"gimp:" instead of "gimp-" so we follow the GEGL prefix style and
better serialize to XML.

* app/tools/gimp*tool.c

* app/core/gimpdrawable-*.c
* app/core/gimpdrawable.c
* app/core/gimpimagemap.c
* app/core/gimpprojection.c: Changed accordingly.
