This PR adds support for dynamic fixtures, which are yml files with Ruby code in them. Rails supports this so we also want to support this.
Before this change, Ruby's yml parser, Psych, would raise
Psych::SyntaxError
when attempting to parse non-valid yml. This change attempts to parse yml normally, but if it fails will run the input through the Erb evaluator and then attempt to parse the output using Psych.Addresses #149
