handle deep plugin homepage when searching for latest release

[dgreif]

The homebridge-ring plugin hasn't been showing the initial release notes before updating for a while now. Finally took a second to track it down and it looks like it's because my homepage url is a little non-standard: https://github.com/dgreif/ring/tree/master/homebridge#homebridge-ring. Took a more generic approach to your url parsing and look specifically for the user/repo parts of the url using regex. Still works for homepages with #readme (or any other #) at the end

Just thinking about it more, should it use repo.url from the package instead of homepage? Seems like that would be more reliable, especially if someone had a custom homepage hosted elsewhere.

Thanks!
