This fixes the officially accepted message types for `assert.throws()`,
`assert.rejects()`, `assert.doesNotThrow()` and
`assert.doesNotReject()`. It also renames the `block` argument in
those functions to `fn` and `promiseFn` for further clarity.

1) Switched + / - and red / green in diffs. It seems like that style
is more natural to most people.
2) Short primitives do not use the diff anymore. Especially short
numbers can be read well like 1 !== 2. Cases that can not be
displayed like that (e.g., -0 and +0) use the regular diff output.
3) Improved error descriptions. It was not always clear what the
messages stood for. That should now be resolved.
4) Added a position indicator for single lines in case a tty is used
and the line is shorter than the visual columns.
5) Color detection is now done by checking stderr instead of stdout.
