Goto and Definition Retrieval

[rosenbrockc]

The fortpy.el file has support for getting definitions and navigating to definitions in code files. Fortpy doesn't support this yet. We have the character and line functions and attributes already available to do this easily, we just need to implement it.

Also, the goto from fortpy.el still has some complicated remnants from jedi that we don't need. Python needs lots of recursion to give good isense support, but Fortran doesn't. Our goto recommendations will be extremely precise and we don't need all the recursion support. Those methods can be deleted from fortpy.el or updated to work with it.
