Fixing the submit render for models/text
= submit render now has arrays to map submit handles to scene list indices for models/text
= linked list iterator pastbegin/end replaced with done, which is true anytime the iterator is no longer valid
+ (proper) remove method for linked lists
= calls to set size will set new capacity to max of new size and 1.5 time capacity
= added more objects to the scene for testing
= adjusted lighting
