Title: Allow logging to be sent to a file

In config.rb, you can write:

```ruby
logger 'middleman.log'
```

It's not the best - I'd rather have the logfile be a config setting (along with log level and instrumenting) but this is the best I can do right now without major surgery. This should help #1004 if not completely solve it.
