Support for lower case CL variations.



Further changes have been pushed for the support of CL implementations with a mode or variation in which the standard CL symbol 
names are lower case.  This has been tested on a Scieneer CL variation and passes all the tests.  An attempt has also been made to 
support Allegro CL modern mode, but this is untested - if there are any issue then please let me know and they should be simple to 
correct.
