Make 'tag' optional, or allow 'HEAD' or specific revision

[iljaiwas]

There are authors on GitHub who don't like to tag their code releases. That makes it quite cumbersome to use their code from CocoaSeeds.

Can we get a little more flexible with the "tag" required, e.g. allowing for "HEAD", or a specific commit hash would be awesome.

Thanks for considering.

+1, a specific commit would be great!

@iljaiwas, It'll be great if CocoaSeeds supports downloading sources from specific commit. Alternatively, CocoaSeeds currently supports branch.

I'll soon make it available :)
