[TxMt] Additional Keyword support for SQL Language

[Mark Cotner]

This was my first stab at editing a language
definition.  I tried to add "COPY" support as well,
but couldn't get it to work for whatever reason.  This
version supports most keywords in the spec.  I'll try
and add better stored procedure/function support as
well as get copy working and respam.

'njoy,
Mark
