Hotkey modifiers don't work correctly & F12 hotkey problem

I've made some tests on last 1.1.1 (Win7-64) and revealed the following thing in using Env.addHotkey function:

#1. There is a little mess with key modifier using in addHotkey, for example:

         Env.addHotkey(Key.F11, KeyModifier.CTRL, handler) # works as expected
         Env.addHotkey(Key.F11, KEY_CTRL, handler) # works as expected too
         Env.addHotkey(Key.F11, Key.CTRL, handler) # fails

         # another example:

         Env.addHotkey(Key.F11, KeyModifier.WIN, handler) # doesn't fail but doesn't work as expected
         Env.addHotkey(Key.F11, KEY_WIN, handler) # works as expected
         Env.addHotkey(Key.F11, Key.WIN, handler) # fails

This needs to be standardized (an issue with obsolete constants). Also in removeHotkey function, I suppose.

#2.
         Env.addHotkey(Key.F12, 0, handler) # see below

This is passed but generally doen't work on Windows. The solution is to change system debugger hotkey in the registry: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug\UserDebuggerHotKey from 0 to any suitable value (0x2F for example), then reboot; this will turn off the debugger hotkey F12 and release this key to use as Sikuli hotkey.

Also SHIFT+F12 hotkey can't be set without registry tweaking. But CTRL+F12 can be successfully set, I did it on my Windows 7 machine.
