Title: Change from round(...) to Math.floor(...) when calculating relative number of months

I noticed that:

```
moment('2012-02-01T00:00:00').from('2012-12-11T11:29:59') == "10 months ago"
//but...
moment('2012-02-01T00:00:00').from('2012-12-11T11:30:00') == "11 months ago"
```

I expected `10 months ago` in both cases (this is the behaviour of `time_ago_in_words` in Rails). I've made a small change which changes this behaviour. I haven't had a chance to run the full sweet of tests as I'm not on my development machine, but I thought I should open this pull request for some feedback as to weather this change in behaviour is appropriate for Moment. If so I'll go through and fix anything this change breaks!
