altered the syntax of unsigned num (do not reply on passthrough)
some cleanup of the number grammer, also added export value translate
csharp: translating uints to '\uXX' chars

This gets us through a -T0 tranlation. What we really need though is a syntax
for char-typed values. Probably start with three basic types: unsigned, signed
and char. Using u(N), N and c(N).
added a char value type, use it to write out character vals in c#
c# test case translator now working for all test cases
going to do a full walk of trans::stmt in each test case translator
simplifying indep::stmt
refactoring grammar items out of trans::stmt
removed action_block from trans::stmt
trans-*: expanded the print statements
trans: clearing out some unsued literals and grammar forms
