Mocha-lcov now has file pushing capabilites

[Quazie]

Based off of work in peerigon/xunit-file mocha-lcov-reporter can now write to a file.

Hi @Quazie. Thank you for the pull request. I'm curious though, isn't redirecting the output to a file sufficient?

[Quazie]

There are a number of ways to get Mocha running multiple reporters at once ( I am using the pull request associated with mochajs/mocha#930 ) - by having the reporter automatically report to a file I can use stdout for something useful to look at such as the spec reporter

@Quazie I'll merge it as soon as the mochajs/mocha#930 pull request itself is merged.

I am a bit hesitant as I don't want to cause any headaches for the current users of the mocha-lcov-reporter. It tries to open the file config.json. The reporter (probably, haven't tested it yet) errors when it can't find the file. Later this week, I'll take a look at it.

For now, isn't running mocha multiple times sufficient? I'm guessing you are using the coverage data either in a CI environment (in this case, running it multiple times doesn't seem to be that much of a problem), or are using the coverage data in an IDE which is continuously updated (in this case, multiple reporters minimizes the required background work.)

[Quazie]

For now i'm using my branch, so realistically I'm fine without this being merged in yet - I just have found things like xuint-file to be very helpful, so I decided to give back my adaptation of your code.

@Quazie FWIW, the reporter was just changed in a way it's easier to override how it presents its output: #16 I think that can allow you to do what you wish even without modifications to the code (I believe our motivations were similar).
