shift/ctrl/alt hotkeys

[atan59]

Presently it's posible to assign talents/items to <shift>-# keys, and use them as expected, which is a good thing (especially for mages). It would be awesome if when pressing <shift> by itself, the 1-12 hotkey menu on the lower right side of the window was replaced by its <shift>-ed version, so you could see what's assigned and the status of the talents. Same goes for <ctrl> and <alt>,of course, but doubling the amount of visualizable hotkeys would already be great.
