Other

Updated third party libraries:
- d3.js 3.4.1 (AMD definition upstream in mbostock/d31689)
- es5-shim.js 2.3.0
- highlight.js 8.0
- leaflet 0.7.2

Major Changes
- The primary change since 0.4.2 is the reorganization of the JavaScript modules to a more standard AMD layout (12). This change makes `lib/` the AMD/RequireJS `baseUrl` so third-party libraries can be require()d via their standard names (`jquery`, `leaflet`, etc) rather than the old non-standard `wq/lib/jquery` style paths. [wq init](http://wq.io/docs/build), the [tests](https://github.com/wq/wq.app/blob/master/tests/), the [documentation](http://wq.io/docs/), and the [project template](https://github.com/wq/django-wq-template) have all been updated to reflect this new layout.

- marked 0.2.10
- mustache.js 0.7.3
- proj4 2.0.0
- proj4leaflet 0.7.0
- requirejs/r.js 2.1.9

New Modules
