Make dependency on rugged optional

[sschuberth]

Now that there is support for filesystem-based projects, how about making the dependency on rugged optional, and only use it if it's already installed? The main reason for this being that rugged, as a native extension, can be a pain to install on some platforms, and after all a Git working tree can also be scanned by the filesystem scanner.

@sschuberth makes perfect sense. Any interest in submitting a pull request to do just that?

[sschuberth]

@benbalter Interest yes, although I do not yet know how to technically do that, nor do I know when I would have some time. So if you have a clear idea how to implement it, please go ahead and do so. Otherwise I'll play around when I find some time.

@benbalter @sschuberth any idea how to deal with this? If it's quick I'd be glad to submit a PR. The dependency on rugged is making it very difficult for me to install this project.

I should note I'm not a Ruby expert so I might need a few pointers for things that could seem basic. I can use Ruby but I'm much more versed in Node.js.

Ok, in my particular case I was able to successfully install licensee in my system after installing the cmake and openssl-devel dependencies (using yum in my case). Maybe this will help others running into issues.

Another thing that would help here is to talk the rugged people into publishing pre-built binary gems for rugged.
