Bugfix: EXLTA_addTabBySelector was injecting new tabContainers one level too high in the DOM tree (MOBIL-67).
Added some comments to a EXLTA function that seems buggy?
Renamed method kBFixTabs => kbFixTabs
Calling kbBootstapifyTabs from EXLTA_openTab.

Fixing top buttons in the help tab (add for MOBIL-67).
