Better error handling when kernel crashes due to overridden built in modules

[DonJayamanne]

Fixes #8195
Fixes #5896
Fixes #6791

• Display message prompting user to rename file if kernel fails to start due to some funky file in workspace
• Better handling of cancellation (if user stops kernel startup, then cancel all of the kernel startup code early)
  • Came across this when testing kernel failures (constantly running & causing cells to crash/fail)
  • Now cells stop running immediately when you decide to switch kernels & things are killed much earlier/quicker (previously we'd wait to start the kernel & then kill it)

This is no longer required, was only required for python 2.7
Also ipython_genutils is no longer shipping in conda

Did these all move here from somewhere else?

Moved from errors.ts, but some of the code is new

Is this another goofy spelling difference? Analyze is with a 'z' afaik.

Damn it, sorry, will change.

Probably dont want to submit this. Although I think the test just overwrites it each time.

Oops.
