Configure kleopatra with different application name for GPD and VSD
* src/gpg4win.mk.in (kleo_icon_dir): Rename to... (KLEOPATRA_ICON_DIR): ...this. (KLEOPATRA_APPLICATION_NAME): New. * src/Makefile.am (gpg4win_pkg_kleopatra_configure): Add -DKLEOPATRA_APPLICATION_NAME option. Replace kleo_icon_dir with KLEOPATRA_ICON_DIR.
Using different application names for kleopatra for GPD and VSD makes
it possible to run kleopatra built for GPD concurrently with kleopatra
built for VSD (and concurrently with kleopatra built for Gpg4win).
