[patch] INIT_OVERLOADED_CLASS_ENTRY fix

Hey, The attached patch adds support for passing a variable to INIT_*CLASS_ENTRY in the name field (instead of just passing a constant string). I've needed this for a function which provides API functionality, registering classes with Zend based on the information passed to it. -Sterling Ps: The Midguard folks needed this feature/ran up against this wall awhile ago as well. Its the only reason I was able to find the problem without hours of painful debugging ;-)
