Also makes mainFields configurable when using register.
The naming is open to bikeshedding…

@jonaskello can we make some progress here? The PR has been open for 6 days…

Also, we discovered a real bug when using the match-all in our register hook:

1. fork-ts-checker-webpack-plugin does a require('tslint')
2. tsconfig-paths’ match-all rule resolves this to <root>/tslint.json
3. things blow up because obviously you wanted to require the tslint module, and not your tslint config file…

[tomspeak]

Facing this issue too. Start up time takes a huge hit when requiring tsconfig-paths.

[jonaskello]

Ok lets merge this, sorry for the delay!
