	* app/plug-in/gimpenvirontable.c
	(gimp_environ_table_case_insensitive_hash)
	(gimp_environ_table_case_insensitive_equal): Win32-only case-
	insensitive hash and equality functions.
	(gimp_environ_table_load): On Win32, use the above functions for
	the vars hash table. This fixes the problem that occurs when the
	actual PATH environment variable is spelled Path (as it seems to
	often be), but the default.env file as set up by the installer
	provides PATH. They didn't match so both would be passed to the
	plug-in child process, and apparently which one then was used to
	look for DLLs was more or less random. If it was the original
	Path, it didn't contain the directories the installer put in PATH
	in default.env, and plug-ins didn't find the DLLs.
