This changes some functionality but it shouldn't cause too many issues
since the previous functionality was kind of a hack anyway.
This also adds a simulation conditional hook that has only been
available through global hooks before.
This adds a utility library for handling all the nasty lua referencing
stuff. It also provides functions for convienent usage of lua objects
such as tables and functions which allows to use them directly from C++
code without using the ugly Lua C-API.
