SqMod/shared/Base/Utility.cpp
Sandu Liviu Catalin f1d8d60e96 Improve the string retrieval from the stack to make use of the new sq_getstringandsize API function and also obtain the size everytime.
Add two new helper functions to retrieve the string representation of a certain script type or object.
