Fixed tests so that they run properly

[lukaso]

However, the result is not a working app. The main thing here is I got the tests running and got rid of warnings. I did this all on Ruby 2.1.3

I had to comment one test out because it couldn't figure out how to build 'pkg' but then when I go to build again, I have to rm -rf pkg anyway to get the app to build again.

Hope this helps (and sorry I forgot about the topic branch). Started committing on master before I thought it through.

This is the test I commented out, because I couldn't figure out what it was doing.

I can't remember what it was doing...

Mmm.

As I pointed out, the exclusion of bundler is correct.

Well, one problem is that the OSX wrappers are only for Ruby 1.9.2, so no gems compiled for 2.x (or 1.8.x for that matter) would work on that platform.

I think the gosu osx wrappers might be for ruby 2 now, but I'm not sure. I haven't gotten it working so can't really vouch. Here's a ruby 2.1.2 wrapper: https://github.com/jlnr/ruby_app/releases/tag/v0.7.50

From the comments:
• Ruby 2.1.2p95
• Gosu 0.7.50
• OpenGL 0.8.0 (or 0.9.0; not sure)
• Chipmunk 6.1.3.1
• Ashton 0.1.3
• Texplay 0.4.4 (the binary for PowerPC is missing, contact me if this is an issue)
• Requires 10.8 for 64-bit Intel, 10.6 for 32-bit Intel, 10.5 for 32-bit PowerPC
