Web Client main skeleton minus working AJAX

Adding the (currently empty) music table, basic player controls, and a temporary button for the profile modal. The profile modal's static content is complete, and only requires the JAX-RS and proxy code to be implemented to handle the AJAX calls from the modal, such as updating user info and listing/add a new MPD connection.

This is Sublime's fault, I think. Sometimes it likes to switch back to tab size 4. Right now everything's showing up at tab size 2 on my computer.
