Make tester work with @types feature

[kant2002]

There upcoming feature in the upcoming Typesscript 2.0 which allow use node_modules/@types folder to store TypeScript definitions and there already exists porting efforts to that stratecy of deliverying TypeScript definitions. See https://github.com/DefinitelyTyped/DefinitelyTyped/tree/types-2.0

Current tester not working with new definitions because it could not resolve definitions using ///<reference types="..." /> format.

Would be reasonable to make this work for this scenario too.

I make this work by modifying src/tsc/Tsc.ts file by including additional command line options --typeRoots . --types jquery. That's very dirty, and just to give proof of concept. Full fix should include additional parameter which to dt and some other changes probably should be required on TypeScript side.

Now more about the change:

1. Make root folder of DefintelyTyped as source folder for definitions --typeRoots .
2. Fix error in the latest TypeScript which gives following error

error TS2688: Cannot find type definition file for '.git'.
error TS2688: Cannot find type definition file for 'gsap'.
error TS2688: Cannot find type definition file for 'node_modules'.
error TS2688: Cannot find type definition file for 'scripts'.
error TS2688: Cannot find type definition file for 'swipe.js'.

if some dummy existing types module does not provided. That's why --types jquery
