Big changes to CJT version 11.4

Any fresh installs of CJT Free version 11.4 will no longer have the Aux and Adv tabs, while existing CJT Free users will continue to be able to use them. The Aux and Adv assignment panels will now only be available in the CJT PLUS edition. Apart from this major change, we have made a number of fixes to some editor tools and also implemented a new tool button popup library that is faster and more responsive.
