[Bf-committers] better keymap display proposal

[Jatz]

Hi, I've been thinking about this for a while. the keymap helper that
shows up in the menubar while an operator is active isn't ideal. if
the region isn't big enough you can't even read all of it. the
carvermt addon does a slightly better job by displaying the current
keys in the viewport. i think thats the direction we ought to be
moving in.

first time for me posting here.
