Added ability to send custom stack traces to _ratchet.push

[loganvolkers]

I went above and beyond to re-use some methods, and made the object detection work with iframes/popups.

This should also probably be added to the documentation somewhere.

var trace = {
  exception: {'class': 'com.example.ErrorType', 'message': 'Somebody borked my stack trace'},
  frames: [
    {'filename': 'FancyClass.coffee', 'lineno': 104}, 
    {'filename': 'ImportScript.ts', 'lineno': 102},
    {'filename': 'CompiledGwt.java', 'lineno': 102},
    ...
  ]
}
_ratchet.push({_t: 'trace', trace: trace})

Awesome. Will review and test this tonight.

Aside from the one comment about trace.frames vs. trace.trace, looks good. Make sure to check that in your usage.

Will finish testing and push this out to production tomorrow (pacific time). Thanks again!

@brianr I'm using trace.frames, but just blindly copied trace.trace into the comments.

@loganvolkers ah cool, figured that might've been the case.
