The scrap allocator works better if taller rects are allocated first (so
long as they're not too tall, more tuning needed) and qplaque is taller
than mainmenu (but draw order is reversed).
This has smashed the keydest handling for many things, and bindings, but
seems to be a good start with the new input system: the console in
qw-client-x11 is usable (keyboard-only).
The button and axis values have been removed from the knum_t enum as
mouse events are separate from key events, and other button and axis
inputs will be handled separately.
keys.c has been disabled in the build as it is obsolute (thus much of
the breakage).
Other than its blocking of access to certain files, it really wasn't
that useful compared to the functions in qfs, and pointless with access
to qfs anyway.
F6 is fantastic, until you hit it by mistake after dieing when you meant
to hit F9 (I've done that way too often). quick.sav is still the last file
written via F6 (so F9 is unaffected), but now the previous quick.sav
becomes quick1.sav. Up to 5 (currently) backups will be kept: quick1 is
the newest, quick5 the oldest. A menu for accessing the backups has been
added as a sub-menu of the load menu.
