unminify dependencies and upgrade

With this change all the bundled dependencies are included in their
unminified form to ease debugging and the asset pipeline, by default,
will use UglifyJS to minify them for production when debug mode is
turned off.

Additionally, the dependencies were upgraded where possible. The
current versions are as follows:

- AngularJS v1.0.4
- Annotator v1.2.6
- d3 v3.0.5
- easyXDM v2.4.17.1
- jQuery v1.8.3
- jQuery Mousewheel v3.0.6
- jwz 26aeec1
- underscore v1.4.3

The heatmap had to incur a slight change to accommodate the d3 upgrade.

Fixes #253

+ * js_channel is a very lightweight abstraction on top of
+ * postMessage which defines message formats and semantics
+ * to support interactions more rich than just message passing
+ * js_channel supports:
+ *  + query/response - traditional rpc
+ *  + query/update/response - incremental async return of results
+ *    to a query
+ *  + notifications - fire and forget
+ *  + error handling
+ *
+ * js_channel is based heavily on json-rpc, but is focused at the
+ * problem of inter-iframe RPC.
+ *
+ * Message types:
+ *  There are 5 types of messages that can flow over this channel,
+ *  and you may determine what type of message an object is by
+ *  examining its parameters:
+ *  1. Requests
+ *    + integer id
+ *    + string method
+ *    + (optional) any params
+ *  2. Callback Invocations (or just "Callbacks")
+ *    + integer id
+ *    + string callback
+ *    + (optional) params
+ *  3. Error Responses (or just "Errors)
+ *    + integer id
+ *    + string error
+ *    + (optional) string message
+ *  4. Responses
+ *    + integer id
+ *    + (optional) any result
