21ad06b1e1 Remove unwraps and clean up playground
The original intent of this patch was to remove more unwraps to reduce
panics. I then lost a ton of time to the fact that the playground isn't
in a temp directory (because of permissions issues on Windows).

This commit improves the test facilities to:

- use a tempdir for the playground
- change the playground API so you instantiate it with a block that
  encloses the lifetime of the tempdir
- the block is called with a `dirs` argument that has `dirs.test()` and
  other important directories that we were computing by hand all the time
- the block is also called with a `playground` argument that you can use
  to construct files (it's the same `Playground` as before)
- change the nu! and nu_error! macros to produce output instead of
  taking a variable binding
- change the nu! and nu_error! macros to do the cwd() transformation
  internally
- change the nu! and nu_error! macros to take varargs at the end that
  get interpolated into the running command

I didn't manage to finish porting all of the tests, so a bunch of tests
are currently commented out. That will need to change before we land
this patch.

0dc4b2b686 Add support for external escape valve (^dir)
This commit makes it possible to force nu to treat a command as an external command by prefixing it with `^`. For example `^dir` will force `dir` to run an external command, even if `dir` is also a registered nu command.

This ensures that users don't need to leave nu just because we happened to use a command they need.

This commit adds a new token type for external commands, which, among other things, makes it pretty straight forward to syntax highlight external commands uniquely, and generally to treat them as special.
