- Replaced string malloc()... calls with strmemcpy() from strext.h where appropriate - Added table name to column struct (useful for WHERE's) - Changed the column type enum to powers of 2 (potential for NULLABLE flag by or'ing) - Added last_qry and num_queries to connection struct - Fixed destruct tables stopping on error - Renamed owners to users except in the meta table - Fixed the 'tableExists' query
