CORE-1302 MySQL syntax for autoincrement column with start value. Fix for CreateTableGenerator. (see detail..)

The generic getAutoIncrementClause() now omits startWith. (through generateAutoIncrementStartWith returns false).
CreateTableGenerator instead stores the last "startWith" value and appends it after the create statement as a "table_option".
Note: By this change even the AddAutoIncrementGenerator generates a valid MySQL statement - however, without setting the startWith!!
