Unify racer code completion format

Makes all the suggestions on the completion menu have the same format:
  {type}{suggestedWord}{extra description}

the type column is aligned to 6 characters wide (and aligned to the right),
to allow the suggestion to be easily visually detectable and, as a bonus,
the type too.

For example, a bit of menu would look like this:
        fn stdout() -> Stdout
     trait BufRead: Read
    struct BufReader<R>

Type is one of the following:
  -     fn
  -   enum
  -    mod
  -  trait
  - struct

It also trims the module extra bits to only 30 characters long (it can be a lot longer than that)
