Printf now has long (64-bit), char, and % literal support. I haven't written
anything specific for shorts yet but if you cast it to an int on the way
in, it'll work anyway, so whatever.
Many code changes, many undocumented. Documentation and cleanup is next.
Fixed a lot of bugs related to IDT structure. Changed the IDT paradigm
to be dynamically written isntead of statically to account for nobits on
that section.
Also added a gdb remote debugger automatic script, for simplicity in
debugging.
