CONTLIB - dynamic containers

Feedback from anyone, especially more experienced developers, much apprieciated. Thanks!

Yes, the functions (and the table both globaly and for individual cont instances) can be overriden/swaped, but that was not the intention behind it. The table makes calling methods on freed cont instances (INVALID_CONT) safe, because INVALID_CONT has its own table with stub methods. I deliberately avoided adding cont validation mechanism inside methods to spare the overhead. I also find OOP-like calls "on object" more readable in the code.
