Implemented charmap stack

Browse Source 
New commands:
 .PUSHCHARMAP: will push the current charmap state into an internal stack
 .POPCHARMAP: will restore the current charmap to the last pushed charmap

Details:
  The push and pop facilities are implemented directly inside the tgttrans.h,
  to facilitate its reuse on the C compiler.
