Template lookup does not work for Rails engines

[gregorw]

When developing a Rails engine, the server is started from spec/dummy or test/dummy. However, the view lookup expects the root directory.

See https://github.com/apotonick/cells/blob/master/lib/cell/templates.rb#L24: return unless File.exists?("#{prefix}/#{view}")

Here, prefix is something like app/cells/mycell, but Dir.pwd is spec/dummy. So, the view template in app/cells/mycell/show.slim is never found.
