- renamed thingdef_codeptr.cpp and moved it out of thingdef/.

Ultimately, thingdef should only contain code that is directly related to the DECORATE parser, but that's not the case with this file. It's only function definitions which get used during gameplay and will also be accessed by ZScript.
The change is intentionally on master so that pull requests can adjust to it now instead of creating conflicts later.
