app/dialogs/Makefile.am new files implementing the channel options dialog 

2004-10-19  Michael Natterer  <mitch@gimp.org>

	* app/dialogs/Makefile.am
	* app/dialogs/channel-options-dialog.[ch]: new files implementing
	the channel options dialog with a horrid number of 13 construction
	parameters. Still better than having the same code twice, only
	differing in strings used...

	* app/actions/channels-commands.c
	* app/actions/qmask-commands.c: removed the dialog code here and
	use channel_options_dialog_new().
