Jskad supports <7, >8, etc. again; it no longer supports the punctuation

'<' and '>'.  The current keyboard implementation makes this an either-or
proposition, when fundamentally it need not be.

Added a <?Numbers?> command and an <?Input:Numbers?> command to
tibwn.ini; broke the numbers apart from the consonants.  This facilitates the
new-and-improved Tibetan->Wylie conversion.

Tibetan->Wylie is now done by forming legal tsheg-bars.  A legal tsheg bar
is converted into perfect THDL Wylie.  See code comments to learn what
it thinks is a legal tsheg-bar, but it inlcudes bskyUMbsH minus the trailing
punctuation (H), e.g.

Illegal sequences, such as runs of transliterated Sanskrit, are turned into
unambiguous Wylie; each glyph is followed by a vowel or a disambiguator
('.').

I've made it so that the illegal sequences are as beautiful as possible.  You
get 'pad+me', for example, not the equivalent but uglier 'pad+m.e.'.
