Marcus Wanners 3abe591195 Fixed a small bug with the overlaid framerate: If the float fps in the infobar is 60.00, the overlay shows 60. If it is something like 60.04, it shows 61. If it is something like 59.13, it shows 60. 
Also deleted Externals/wxWidgets/lib/vc_lib/msw/wx/msw/rcdefs.h, it must have been versioned at some point by accident, causing issue 706.
