	Cleaned up all places which pick colors to work consistently: the
	concept of an "active color" has disappeared, instead <ctrl> picks
	the BG color all over the place (fixes bug #122931).

	* app/tools/tools-enums.[ch]: added enum GimpColorPickMode which
	can be one of { FOREGROUND, BACKGROUND }. Reordered enums so
	non-registered ones are at the end of the file. Removed trailing
	whitespace.

	* app/tools/gimpcolorpickeroptions.[ch]: added a "pick-mode"
	property and a GUI for it. Renamed the "update-active" property to
	"update-toolbox".

	* app/tools/gimpcolorpickertool.c: honor the new option. Toggle
	pick-mode on <ctrl>.

	* app/tools/gimpcolortool.[ch]: added pick_mode member and change
	the cursor accordingly.

	* app/widgets/gimpcolormapeditor.[ch]: added "GdkModifierType
	state" to the "selected" signal. Removed the signal's default
	implementation.

	* app/gui/dialogs-constructors.c: fixed the signal handler which
	lives here and set BG if <ctrl> was pressed.

	* app/widgets/gimppaletteeditor.c: removed weird <ctrl> <->
	active_color interaction and pick BG on <ctrl>. Don't change the
	toolbox color when editing a color in the palette.

	* app/widgets/gimptoolbox-color-area.[ch]: made the whole
	active_color stuff private. Will remove these artefacts soon...

	* app/gui/colormap-editor-menu.c
	* app/gui/palette-editor-menu.c: added separate menu entries
	for adding a color from the current FG and BG.

	* app/gui/colormap-editor-commands.c
	* app/gui/palette-editor-commands.[ch]: changed callbacks
	accordingly.

	* cursors/background.xbm
	* cursors/background_mask.xbm
	* cursors/foreground.xbm
	* cursors/foreground_mask.xbm
	* cursors/gimp-tool-cursors.xcf: moved the FG/BG cursor modifiers
	closer to the upper right corner.

	* app/widgets/gimpcursor.c: ignore the cursor modifiers' hotspots
	since they are not relevant and I didn't save the hotspot in the
	updated cursor files for that reason.
