Fixed up EventData
This is a breaking change, I didn't pay attention when merging. Many
function names are changed from natives, but some are not. Also some are
simply not correct, like getMouseScreenPos(). It does not return screen
pos. I'm wondering whether most of these wrappers are useful at all, or
if we should only provide getters for custom data sets, e.g. the vector
positions. hm.
