Title: Add jump to definition command by parsing info

Added a command that parses out the location of a definition from the info, and jumps there. It would be nicer to add support for this feature directly in ghc-mod, but the Haskell code in there is scary :).

Also, Emacs' regex functions are really weird, not sure if repeatedly calling `string-match` is the best approach.
