Minor Improvements

I've removed the dependency on water.css and slightly changed the generated page style. It saves a HTTP request of 4kb (compressed). But more importantly it removes a dependency. It's one thing less to know about and keep updated. Fighting every dependency seems like a good approach for side projects. You only have to know the things you built yourself. You can build them to do exactly what they need to do, nothing more and nothing less. But this only goes so far: Daily needs to sanitise user input. That's not something you should build on your own. It makes more sense to rely on a community effort to catch all those corner cases.
