`rustlings list` should now display more than just the exercise names.
Information such as file paths and exercises statuses should be displayed.
The `--paths` option limits the displayed fields to only the path names; while the `--names`
option limits the displayed fields to only exercise names.
You can also control which exercises are displayed, by using the `--filter` option, or
the `--solved` or `--unsolved` flags.
Some use cases:
- Fetching pending exercise files with the keyword "conversion" to pass to my editor:
```sh
vim $(rustlings list --filter "conversion" --paths --unsolved)
```
- Fetching exercise names with keyword "conversion" to pass to `rustlings run`:
```sh
for exercise in $(rustlings list --filter "conversion" --names)
do
rustlings run ${exercise}
done
```

This should also fix#465, and will likely fix#585, as well.
That bug mentioned in those issues has to do with the way the `watch` command handler fetches the pending exercises.
Going forward, the least recently updated exercises along with all the other exercises in a pending state are fetched.
This new feature can be accessed by invoking rustlings with --nocapture.
Both unit and integration tests added.
closes#262
BREAKING CHANGES:
The following function take a new boolean argument:
* `run`
* `verify`
* `test`
* `compile_and_test`
The completion message is shown only once all exercises succeed and are
not annotated with "I AM NOT DONE." The watch command will also exit
closes#251
Hints are now accessible using the CLI subcommand `rustlings hint
<exercise name`.
BREAKING CHANGE: This fundamentally changes the way people interact with exercises.
BREAKING CHANGE: This changes the way you use `rustlings run` by now
requiring an abridged form of the previous filename, e.g:
`rustlings run exercises/if/if1.rs` becomes
`rustlings run if1`
If someone is sliding in and out of "watch" mode, it can make it hard
to tell which error messages are still relevant. This patch resolves
that by clearing the terminal entirely before entering watch's loop.
Before, rustlings would panic if it wasn't in the right directory. It
took me a minute to figure out why, and this wasn't my first intro to
Rust. It would probably help new users if they saw a helpful message
instead of a stack trace.
