Still a lot more to do but pushing WIP to not have it wasted if more
commits come in from others.
Also got rid of some global variables.

None of our load plug-ins have such a checkbox, so this is not
consistent. Moreover one you uncheck it, you just can't get back the
dialog until next GIMP restart. That's very bad usability.

This commit fixes the following error:

Instead, if we want new items in menu, we should use
gimp_plugin_menu_register(). I add the calls, yet comment them out,
since I don't think we want these various conversion calls into the
provided filters. The proper way for data conversion should be through
babl/GEGL.

This is still very broken and it doesn't load well. But at least it
compiles!
All build errors (and a few warnings though not all) fixed.
