2004-04-16  Sven Neumann  <sven@gimp.org>

	* plug-ins/common/Makefile.am
	* plug-ins/common/plugin-defs.pl
	* plug-ins/common/AlienMap.c: removed the AlienMap plug-in since
	AlienMap2 duplicates its functionality.

	* plug-ins/common/AlienMap2.c: applied patch from William Skaggs
	with a couple of user interface improvements (bug #140079).
