Matt Burke c94edb6b2d VAXStations: Improvements and bug fixes to keyboard and mouse devices 
Whilst working on a new video device I ran into a few problems with the
LKxxx keyboard and I noticed there are already some open issues against
the keyboard and mouse devices. These changes should resolve #320 and
may help with #272 (although I think that is an SDL issue). I've tested these
changes with VWS, UWS and DECwindows with both captured and
uncaptured input modes.
