Subject: [PATCH] Implement a single global instance of TDEHiddenFileMatcher,
 available to all applications that do not require their own class instance.
 Match criteria defaults to duplicating traditional dotfile detection but can
 be modifed and extended as desired.

Criteria is stored ${TDEHOME}/share/config/kdeglobals. A future TDE
control module will implemented that provides a user interface for
viewing or modifying the global match criteria default.
