Refactor of layout manager to add support for all menus (dirty unstable)

This revision adds a complex test to the 'TestInterpreter.cpp' file to test functionalities such as classes, variable initializations, loops, conditionals and methods in the interpreter. The token parser has also been updated with a reset method in the 'parser.cpp' file for cleaning up any previous state before parsing a new script. This ensures the parser starts fresh for each new parse request. It also improves the debugging process in 'function.cpp' by printing the description of parser errors. Few completed tasks are removed from the TODO list.

-## Memory Leaks
-
-Example program with memory leaks:
-
-```c++
-#include "allocators.h"
-
-void test_call22() { new int; }
-void test_call21() { new float; }
-
-void test_call11() {
-  test_call21();
-  test_call22();
-}
-
-int main(char argc, char* argv[]) {
-  tp::ModuleManifest* ModuleDependencies[] = { &tp::gModuleAllocators, NULL };
-  tp::ModuleManifest TestModule("Test", NULL, NULL, ModuleDependencies);
-  TestModule.initialize();
-  
-  test_call11();
-  
-  TestModule.deinitialize();
-}
-
-```
-If memory leaks were detected it will be loged in the output console.

-Also debug.memleaks binary will be generated in the working directory that can be viewved with MemLeaks Viewver.
