* (bug 2741) replace K_LAST_KEY with MAX_KEYS. K_LAST_KEY is now defined

at 256 for mod compatability reasons.  ioq3-only mods may
             chose to use MAX_KEYS for checking binds in order to get full
             key support, but at the cost of breaking compatability with
             older clients.

* (bug 2741) remove some lingering 256-key hardcoding

* properly check bounds of keynum in Key_IsDown(), Key_SetBinding(),
  and Key_GetBinding()
