[AD] xkeymap fix

[Elias Pschernig <elias@xxxxxxxxxx>]

I'm about to commit the attached patch to stop xkeymap from crashing,
since KEY_MAX was increased and someone coded xkeymap so it tries to
display a NULL pointer in that case (/me looks away). Btw., is there a
reason KEY_MAX is 120, but the highest key is 118? And what is the
purpose of KEY_MODIFIERS ? If some part of the Allegro code assumes only
modifier keys are defined after it, something might go wrong with the
added OSX keys..
