Mocha stack entries not removed properly

[pkozlowski-opensource]

Discussion moved from #40:

Also I noticet that mocha entries are not removed from the stacktrace.
return stack.replace(/\n.+\/mocha\/mocha.js\?\d*\:.+(?=(\n|$))/g, ''); does not work for the following stacktrace:

Error: Expected PUT /api/lists/123 with different data
EXPECTED: {"foo":"bar"}
GOT:      {"_id":123,"name":"New List Name"}

I wonder if we want to maintain all those crazy stack-parsing regexp that break without warning on different browsers (or even with a version change for a given browser....). Maybe we should use something like:

• https://github.com/stacktracejs/stacktrace.js
• https://github.com/fresheneesz/stackinfo

I had a quick look at both libraries but unfortunately those are doing a but too much for what we need atm... Opened stacktracejs/stacktrace.js#90 to see if we can get the relevant part extracted, let's see.
