Subject: Modify screen savers detection that the XSCREENSAVER_DIRS and
 XSCREENSAVER_CONFIG_DIRS variables allow multiple paths.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Likewise, the XSCREENSAVER HACKS DIRS variable used to search
for an screen saver executable can contain multiple paths.

This relates to TDE/tdeartwork#19.
