removes haml as a dependency [fixes #80]

- renames license.
- adjusts version for next release.
- adjusts the gemspec for dependencies and filenames.
found a reference to haml that wasn't removed.
removes some unused paths/files.
shifts some logic from config into the engine.

- moves asset paths into engine (removes the initializer).
- moves mounting the routes into the engine and prepends them so they can't be clobbered with a glob route.

I'm not positive about which version of Rails implemented the route.prepend method, but I think it's ok in 3.1+.
renames some files in the generator.
moves engine definition into the main require.

- this is part of the simplification process, and will eventually get routes moved into it.
adds a dummy app that we can write tests against.
adds test dependencies.

- includes gems that will be needed for the rails apps generated using aruba.
adds functionality for rspec and the dummy app rake tasks.
adds specs for the engine and setup for configuration.

- adjusts engine to use strings for appending asset paths.
adds specs for ensuring the install generator works.
adjusts the example_spec template to point to the correct fixture.
adds working javascript specs for integration specs.
adds integration test that ensures that the tests run.
updates to readme -- information and format.
updates the license to include copyright information for Brad Phelan.
adding travis support.
