Found a couple of cases where some methods silently fail. Now they throw exceptions instead.
Change Log
Fixed the bug where 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.
Fixed the bug where the BlazeGears.createEntity method wouldn't do anything, if the suggested entity ID was already in use. Now it will throw an error in such a case.
