Upgrade to Backbone 0.5

I just read through the diff between 0.3.3 and 0.5.1. These are the most important changes for upgrading Bones I'm seeing:

• Signature of sync() has changed - should be a straightforward adjustment, but it will touch many parts of our code.
• There are a series of changes to setLocation() (now navigate()) that will require rewriting our overrides for hash bangs.
• Controller is now Router - simple find and replace adjustment.

Per offline discussion with yhahn we'll want to hold on an upgrade of hashbang support for a first iteration.

Before investing further in hashbangs (or fragment support in general) we should seriously consider using pushState and a full-server fallback for browsers that don't support it.

I'll start working on this. I'll commit my work to master after branching 1.3. This upgrade will mean we need to go Bones 2.x.x as changes won't be backwards compatible.

I have made some good progress here today and committed my changes. All tests are completing and the example works fine, but I have not fully verified the upgrade yet. I'll keep this issue open until I have finalized porting the application I'm currently using Bones for.

This is done now. Work all committed to master branch.
