Clean up rake file, removing unused packaging tasks
Require the version file
Make skipped tests output in grey
Use Sprockets to compile and serve site assets
Enable a better assets development mode

In dev mode all assets (css, js) should be included separately,
bypassing Sprockets' bundles.
Attempt MySQL compatibility for revision tests
Remove unused #force_encoding method
Add asset helpers to template context
Ensure that contexts default to production environment
Drop support for converting absolute URLs

consistent: refer to assets with relative logical paths and you're good.
