Using the file argument to self.configure in lib/coverband.rb

[ThomasOwens]

This allows a caller of Coverband.configure to not only pass in a block or have a file in ./config/coverband.rb, but to put the configuration file anywhere they want and pass it in as an argument. If the argument is unused, then the existing behavior is preserved. This should make it easier to invoke an application that uses Coverband from any working directory.
