Made WGI_VALUE.name as READABLE_STRING_32 .. otherwise it is a pain to manipulate.

Changed return type of meta_variable to be WGI_STRING_VALUE ... since the meta variable can not be anything else.
Made sure REQUEST_URI starts with one and only one slash
Internal implementation: the _table now compares object
Removed SELF variable ... at least for now
Be sure to provide a REQUEST_URI even if the underlying connector does not.
