Allow option to output unicode characters

[agriffis]

Great idea! Needs a few tweaks and a test. You might look at https://github.com/jmcnevin/rubypants/pull/15 for a pattern to follow... this should be very similar to how that was added.

I added a quick test and fixed the dash test that was failing earlier, aslo simplified the file structure a bit so that there's no superclass mismatch error anymore.

Thanks. I'll be able to look closer and merge in a few days

Thanks Greg. I split this into two changes:

• Commit 2dea6a6 adds options :character_entities. I used Ruby's unicode escape syntax instead of embedding characters directly—this is especially for the :character_spaces option.

• Pull request #17 adds the RubyPantsVersion module and restructures the repo as you suggested to avoid the superclass mismatch. I'll merge this once the tests run in Travis.

Let me know what you think, and I'll plan to release this as 0.7.0

Thanks for the tip! I didn't know commit emails were used for that.
