Added love.keyboard.getKeyFromScancode and love.keyboard.getScancodeFromKey. Resolves issue #982.

Browse Source 
Scancodes represent a physical key independent of the keyboard's current layout. For example, pressing the key located where 'q' is on a U.S. keyboard will produce the key 'q' and the scancode 'q' when using a U.S. keyboard layout, but when using a French keyboard layout it will produce the key 'a' and the scancode 'q'.

Scancodes are useful for creating default controls that have the same physical locations on on all keyboards.
