Add option to skip additional levels in pseudotraceback

[mbergen]

It would be great to have an option for the various check functions to skip additional traceback levels.
This would benefit situations where the actual check is encapsulated into a helper function (e.g. to check multiple things at a time, and not directly done in the test method.

Example:
checkResponse could be omitted in the pseudotraceback

def test_1():
  response = apiCall()
  checkResponse(response, expected)

def checkResponse(response, expected):
  check.equal(response.status, 200)
  check.equal(response.content, expected)

Interesting idea.
I'd probably like it to utilize __tracebackhide__.

Is this something you'd like to implement?

version 2.2.0 honors tracebackhide
