Updated wasm target to 0x1 (MVP) format

[dcodeIO]

I have a commit here that implements the 0x1 format but as there's no license, yet, I am holding back the PR for now to not complicate things even further. Aside from that, thinscript is the most refreshing piece of code I've seen in a while and I'd love to continue working on it!

• Updated output files to use the 'WebAssembly' API

• Added optional tracing to wasm target for debugging purposes

• Fixed a couple of wasm target issues (and probably introduced new ones)

• Extended wasm custom name section support

• Implemented additional convenience utility

• Implemented a few simple wasm specific compiler optimizations

• Tweaked source files for TypeScript syntax compatibility where applicable

• Changed the js target's generated iife signature from (__declare, __extern) to (__imports, __exports)

P.S.: Did I mention how awesome this project is?

@dcodeIO I tried to contact @evanw few times for contributions to this project but there was no reply. Thats why I started TurboScript project.
