Michael Natterer 8005eea835 Remove the "GIMP" from all "Since: GIMP 2.x" API doc comments 
because it confuses gtk-doc and breaks some links. Also change the
"Index of new symbols in GIMP 2.x" sections to be what seems to be the
modern standard (looked at the GLib and GTK+ docs), and update some
other stuff.

* SECTION: gimpcolorbutton
* @title: GimpColorButton
* @short_description: Widget for selecting a color from a simple button.
* @see_also: #libgimpcolor-gimpcolorspace
*
* This widget provides a simple button with a preview showing the
* color.
*
* On click a color selection dialog is opened. Additionally the
* button supports Drag and Drop and has a right-click menu that
* allows one to choose the color from the current FG or BG color. If
* the user changes the color, the "color-changed" signal is emitted.
