(fix) Fixed CPack problem for RPM generation.
(fix) Fixed CPack problem for RPM generation.

The problem was that CPack generates bad RPMs that tries to create system paths thus leading to errors like 'file /usr/share/man from install of passwordsafe-0.99.0_BETA-1.x86_64 conflicts with file from package filesystem'.
This is a well-known problem (e.g., see http://public.kitware.com/Bug/view.php?id=13609).
To fix this, I've added in CMakeLists.txt a rule to let CPack ignore the offending paths.
