Incompatible between ES6-promise thenable and recent PromiseLike change in lib.d.ts

[yuit]

Our Angular2 code-base of RWC uses es6-promise for defining Promise interface as well as PromiseLike definition from our lib.d.ts. With our recent change, Thenable and PromiseLike is no longer compatible.

@rbuckton can you see if reverting the changes to PromiseLike would do?

I reviewed this with @yuit, reverting the change to PromiseLike fixes the issue, and does not impact the improved typing for Promise.
