Improve the LuaController
Changes: * Stops code after a certain number of instructions. * Allows functions, due to instruction counting. * Allows loops and goto with non-JIT Lua (LuaJIT doesn't count looping as an instruction, allowing infinite loops), due to instruction counting. * Removes string matching functions as they can be slow. * Adds some safe functions. * Limits the amount of printing that can be done (to prevent console flooding). * Code cleanup. * More...
