Remove OSF1 / DEC3100 platform support. (#36)

This also removes support for the DEC3100 keyboard, but leaves a
constant behind for it as I'm not sure about re-numbering.
[NBriggs: keyboard type numbers are stored within all sysouts.  Do not renumber supported keyboards, do not reuse previously used keyboard numbers]
