Remove most uses of XCB_CURRENT_TIME

Browse source 
XCB_CURRENT_TIME really should be avoided as much as possible (see
ICCCM).

However, the screen, mousegrabber and keygrabber code have cases where
they really want up-to-date information / want to activate a grab *now*.
These cases are fine with XCB_CURRENT_TIME since they are not related to
some events.
