Adjusted the error message about exceeding legacy module size and removed the code for saving image version 11. Modules using image version 11 still can be loaded. Saving modules always result in an image version higher than image version 11 depending on the size of the module. In addition, some minor performance issues (construction of the error message and the correct list of modules) were fixed.
