Omegle protocol reverse-engineering

Let's reverse-engineer Omegle. PROPERLY!

I could not find a proper, detailed (and up-to-date) reverse-engineerment of Omegle's text chat protocol on the internet, so here, have one made by analyzing the web app (web requests and source code).
The responses are beautified and the query strings split up and URI-decoded for readability.
Note that "query string" refers to parameters encoded into the URL and "form data" to parameters in the POST body which do not have to be URI-encoded.

Javascript value scaling between two ranges
/* Scale a value from one range to another
* Example of use:
*
* // Convert 33 from a 0-100 range to a 0-65535 range
* var n = scaleValue(33, [0,100], [0,65535]);
*
* // Ranges don't have to be positive
* var n = scaleValue(0, [-50,+50], [0,65535]);
*
* Ranges are defined as arrays of two values, inclusive
