Title: Add rspec config to treat symbols as metadata keys with true values

RSpec output contained a warning when I ran the factories spec because
of the `:factory` tag; RSpec 2 expects a hash instead of a symbol. Adding
this line to the config quiets the warning, and allows behavior that
will be default in RSpec 3.
