Fix gemspec

[Cluster444]

The gemspec had some validation errors, removed some of the non-existent files, and fixed the description/homepage fields.

This will let people use git branches from a Gemfile properly.

So funny thing... this isn't the canonical repo, it's just the very first one to be created. The gem isn't really maintained as such, and it doesn't get deployed out of here, so changing the homepage, while probably not harmful, isn't technically correct either.

Is there another way of getting this gem? I was trying to use it with backupgem which depends on runt >= 0.3.0, it pulls down 0.7.0 from rubygems which has syntax errors in ruby 1.9. I was trying to pull down master from this repo as it seems to have the syntax issues fixed, which is where I was getting the gemspec validation errors.

The problem with the homepage wasn't a matter of where it's pointed so much as it was not a valid URL, the homepage was the description, and the description was blank.
