Adds more support for handling require calls in JS
  - able to better support hyperlinks jumping to the referenced file in the require call (can do F3 on require to jump to that file).
  - able to infer the type exported by the required module/file for require calls that aren't just simple strings arguments, but use path.join to build the string up.
Merge pull request #201 from sgtcoolguy/require
