File overwriting

[JoshCheek]

When SiB evaluates a saved file, Atom sees this and tries to update it. Then SiB puts the file back into place, and Atom sometimes freaks out. Either way it's jarring for a user, I'm sure.

There are now events you can hook into. Perhaps it is possible to preempt other events when that particular file changes, or perhaps it's possible to remove it from the set of watched events, and then later add it back in.

Notes I had locally about this:

Preempt file watching to avoid the issue of it seeing the SiB rewrite and freaking out
  this would be done with file events
  possibly removing the file from the list of things being watched altogether, and then readding it.
  test:
    edit file
    in dev console, disable
    independently change the file
    nothing should happen
    enable
    edit
    should see the update
