1.4.3 - Guards against core upgrade bug when events are involved.
1.4.2- Loads bootstrap.js for c126.96.36.199
1.4 - ccm.app.js moved to addFooterItem, cleaner uninstall, fixed make_attributes() typo.
1.3 - Additional attribute and block to pull in ccm.app.js
1.2 - Now tests is a user is logged in before continuing with addheaderItem. jQuery.ui is already loaded if a user is logged in and addHeaderItem should take care of duplicates, but there have been bugs. Hence the theoretically redundant change.
1.1 - Marks compatibility with C5 version 5.5. No actual changes.
