[Fx Tab] -> [Servo]

[jsantell]

Bonus points if it runs in servo, but debugging a servo tab is sufficient.

Needs #9

Tried running it in a servo tab and get a crash.. Here's the log leading up to it:

ERROR:js::rust: Error at file:///devtoolsweb/built/toolbox.js:2991:5: mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create

Got this running with servo as the backend via ./mach run --devtools 6080 https://google.com and the inspector kind of sort of works. The markup tree is displayed but no rule view, and edits don't seem to work. But that could well be limitations of the implemented methods on the backend, I haven't checked yet to see how the same thing works with a web ide connection and a normal toolbox

[bgrins]

Turns out the crash in #4 (comment) was due to a bad pull, updating servo and rebuilding fixed it
