Ts-jest: Create a skipbabelrc / usebabelrc flag

[GeeWee]

We've seen a bunch of issues such as #242 and #252 that relates to ts-jest picking up babelrc files - often files that are not located in the project dir.

I think we should add a flag to not use babelrc files.

I think this flag should be turned on by default, I don't think people expect ts-jest to use their babelrc.

I propose somehing like a "useBabelRC" flag, or something like it, that's set to false by default.

Thoughts?

useBabelRC with a default of false sounds good to me

@GeeWee can I assume you'll be handling?

[GeeWee]

I definitely can, but I'm in the middle of a move so it might be a little while.
