Update to latest TS 1.5.3

I think that latest TS broke typescript-register:

emitFiles is no longer defined on the checker:

var result = checker.emitFiles();

I will try to take care of that issue in the nearest days if noone else is interested.

@psmolinsky please note that the package is deprecated. Use ts-node instead.

You can find the deprecation notice in the README.
