I realized that (according to the documentation) the updateEntity function was working as expected, so I reverted the last fix made to it. Whoops.
Change Log
Reverted the fix made to the BlazeGears.createEntity function in the previous release, because the original functionality was correct.
Fixed the bug where the static version of the BlazeGears.Class._super_ method wouldn't do anything, when it can't find the sought method. Now it will throw an error in such a case.
