X.A.{Grid,Tree}Select, X.Prompt: Fix keybindings like Shift-Tab and similar

Browse Source 
This changes KeyPress handling in these modules to behave much closer to
how xmonad core itself handles keypresses. The primary difference lies
in that xmonad reads raw KeyCode and then converts it to unmodified
KeySym, while these modules used `lookupString` to find the actual
keysyms. As a consequence, key definitions like `(shiftMap, xK_Tab)`
didn't work on many layouts because an actual KeySym for `Shift-Tab` is
commonly `ISO_LEFT_TAB`, and not `Tab`.
