TSconfig support

[Igmat]

Is it planned? Or there are some restrictions for using more common way for ts developers instead of tweaking package.json?

Could you share what you'd like and how that would be different from the current setup? I'd definitely like to improve this.

How about:
Instead of having

"globals": {
      "__TS_CONFIG__": {
        "module": "commonjs",
        "jsx": "react"
      }
    }

You have:

"globals": {
      "__TS_JEST__": {
        "tsconfig": "./my-tsconfig.json"
      }
    }

in preprocessor.js - getTSConfig you can use path module to resolve the file:

const path = require('path');
const config = require(path.resolve(globals.__TS_JEST__.tsconfig));
return tsc.convertCompilerOptionsFromJson(config.compilerOptions).options;

It should actually be optional, and you should automatically get the default tsconfig.json from root.

I'll take a look at this on the weekend or if you want to take a stab at it, I'd welcome a PR :)
