Bug fix #799 revisited

Now we're on the root of the problem. Ghost (OSX) didn't accept rawkeys
for the 1-2-...0 keys on a french keyboard. These have apparently different
symbols on it. (these silly french! :)
This commit intercepts the rawkeys in convertKey() call, and manually
makes sure theyre correctly mapped.

So: now french (spanish, etc) OSX users can finally use layer hotkeys! And
the popup menu shortcuts! :)

Tested & verified by Lukep. Merci!
