A very minor update.
* Changed "stringbox" procedures to allow Unicode characters
* Small changes to DDS to clarify code and very slightly improve performance (fixing a
'bug' that I had created which required holding_t type to be unsigned int rather
that unsigned short
* Allow fully played tricks to be passed with the -trick option to 'dds' command
* Documentation for 'dds' -trick option
* Reorganization of commands documentation file to create a non-framed version
