Definition files in sub folders are not detected

[rhmoller]

When the definition-parser scans for .d.ts files, it should also look in sub-folders.

This affects react-router and other modules. See microsoft/TypeScript#9488

this is tracked by #3

I should add that PRs are always welcomed

It is not entirely the same. #3 is about a structure for maintaining typings for multiple versions of a library.

This issue is about supporting definitions that are split into multiple files with some of the files in a sub-folder
