Show matches count in results

[francoisfreitag]

Displays matches count for each repo and each file in the repo.

Seems reasonable, @kellegous take a look and merge when ready.

Sorry, Haven't been doing my job with these pull requests.

The repo level count is a little different from the file level. It's not sufficient to do result.Matches.length because the Matches array may be shortened due to a range request. You will notice that, by default, hound just returns the first 20 files matched in a repo. You will want to use result.FilesWithMatches instead, which will give you the true number of files that match (not just the ones that were returned).

FYI, this almost works correctly...there's a small mismatch: http://i.imgur.com/YEn7UfO.png One place says "82 files", and the other one says "81 files".

Here's another example where it is "19 files" in one place but "27 files" in the other: http://i.imgur.com/6SN9aXn.png
