missing right key enumerations and bitmap addressing

[Corallus-Caninus]

Cannot bind to right keys

right keys in linux have 0xe0 prepended to them. I cant seem to get is_pressed() to address the bitmap appropriately for scancodes that have a sequence greater than one.

at least the following keys are missing from the enumeration:
right ctrl
numpad enter (KP_Enter vs Return in xmodmap -pke)

I'm working on it but got stuck and thought it worth posting thanks.
