Find a way to bring in TypeScript "source"

[basarat]

Instead of using it from package.json

Motivations:

• I don't like getting locked out: Language Service API review microsoft/TypeScript#2899 Same reason why I'm using the full language service instead of TSServer
• I would (and perhaps you whoever is reading) would like to hack stuff in the compiler and get an immediate feedback in the UI. Currently F12 takes me to a .d.ts that takes a lot of context away from me and I need to open another window and look at the source elsewhere.

This change now makes it impossible for me (or anyone) to easily load in a custom compiler by changing package.json and makes #236 probably impossible to implement.

Yes. But they can equivalently just copy their compiler and services folder. Just a different form of custom compiler loading.

makes #236 probably impossible to implement.

It does seem like it in first look but its actually quite easy. We just need to run their typescriptServices.js a vm context can replace our ts with their ts.

@csnover #236 done ;)
