Added new central krandr library to handle everything related to dynamic screen configuration
In the future this will probably handle ICC profiles as well This will allow easy integration of screen configuration into other KDE programs and control center modules git-svn-id: svn://anonsvn.kde.org/home/kde/branches/trinity/kdelibs@1119941 283d02a7-25f6-0310-bc7c-ecb5cbfe19da
