Fix not including graphmatch directory issue

[pc592]

When attempting to bundle install the gem after adding it to my project's Gemfile, it doesn't include the graphmatch folder (within lib) or the files within graphmatch. Changing the gemspec file seems to have fixed the issue.

This change is unneeded. Both of these result in the exact same list.

Well I still have the same issue, and I've been trying to figure out why it won't work, and I think you may be right, but do you have the built .gem file so that I can test if the .gem file you build works when I specify it specifically?

Edit: actually, wait, I can do that myself, nevermind. I'll update if I ever figure this out.

Edit2: okay so it might be a bundler thing. Still working on it. But it looks like you do need to update the gem on rubygems.org since when I downloaded the gem there and tried to install it it didn't work.
