Experimental BLOB code added - set wxODBC_BLOB_EXPERIMENT to 1 in dbtest.h if you want to help work on this

Browse Source 
Added some more test functions that have no GUI hook yet, but will be used in wxBase buidls eventually
Fixed handling of checks for TableExists() and TablePrivileges() to use the (HOPEFULLY) now working functions.
Better exception handling when the .CFG file does not exist
Better reporting of database errors shown by example
