Add PAWN language

PAWN is a simple, typeless, 32-bit extension language with a C-like syntax. A pawn "source" program is compiled to a binary file for optimal execution speed. The pawn compiler outputs P-code (or bytecode) that subsequently runs on an abstract machine. Execution speed, stability, simplicity and a small footprint were essential design criteria for both the language and the abstract machine.
