Add support for config files with the "yml" extension ("yaml" still works)
Set the default port to 3000 (instead of 5634)

I have also updated the readme to reflect this change.
Set up RSpec with "bundle gem jobim --test"
Set up simplecov for test coverage

Add support for config files with the `yml` extension
 - As `yml` appears to be the defacto standard this is the default now
 - Will look for `yaml` files of `yml` doesn't exist
Merge pull request #14 from thenickperson/rspec

Set up RSpec (test framework) and simplecov (test coverage tool)
