* app/menus.c: include module browser, plus re-instate the 'swap colors' and other options that got killed by mistake. Clean up the odd extra separator too. * app/color_notebook.c: hide newly created colour selectors so we know the GIMP one will be the default page. * app/module_db.[ch]: NEW FILEs: module database / browser. * app/Makefile.am: add module_db.[ch] stuff * app/app_procs.c: initialise the module_db * app/commands.[ch]: callback to create a module browser. * app/plug_in.c: move module loading out to module_db.c * libgimp/gimpmodule.h: API change: module_init() should return additonal info (author, purpose, date, etc.) Also optional module_unload() function. * modules/colorsel_gtk.c: add module info, plus an unload function * modules/Makefile.am: build triangle colour selector module * modules/colorsel_triangle.c: NEW FILE: colour selector from Simon Budig <Simon.Budig@unix-ag.org>. * MAINTAINERS: changed my email address
