Remove requirement to run rake build / rsyncs when changing content

[jamietanna]

When developing locally, and making changes to files in the content directory, we need to either run a rake build while the site is running locally, or manually copy the files.

This leads to a "I've edited this file, why isn't it updating?!?!?" which can be a little frustrating.

We should be able to handle it i.e. with symlinks.
