Title: Be more flexible about excon version.

Every time `fog` updates to use a new version of `excon`, `heroku-api` needs to update in step. That seems silly.

Luckily, `excon` appears to be following semantic versioning. We should be able to use any version with a major number of `0`.

This would save me a whole lot of headaches. I'm sure I'm not alone.
