Introduce the GIT_GUI_LIB_DIR environment variable, to tell git-gui where to look for TCL libs. This allows a git-gui which has been built with a prefix of /foo to be run out of directory /bar. This is the equivalent of GIT_EXEC_PATH or GITPERLLIB but for git-gui's TCL libraries. Signed-off-by: David Turner <dturner@twitter.com> Signed-off-by: Pat Thoyts <patthoyts@users.sourceforge.net>
