Commented Unassigned: Remove need for reference lines [211]

TypeScript no longer requires <reference .../> lines: see https://typescript.codeplex.com/discussions/453886

It would be marvellous if one could use Chutzpah without having to supply <reference .../> lines in the unit test files.

Cheers!
Comments: I put a sample repo here: https://github.com/mmanela/ChutzpahTSReferenceSample This shows using TypeScript with no reference comments.
