Added a non-debug function
Now interpreter works as a loop (as to test changing the bytecode file).
Testing changes from chars to unsigned chars for instruction offsets (always positive)
Added verbose mode (still unimplemented). Changed formats to .fgs for source file and .bfgs for ByteCode.
Added compiler to interpreter. Now you can't compile directly the source files; you have to use the interpreter.
Future implementation of CleanMemory. Changed extensions to .fgs.
Added verbose modes and other changes.
