Deprecate old OneShot functions and public member variables

Deprecates OneShot direct-access configuration variables, and replaces them with
setter functions:

- `time_out` => `setTimeout()`
- `hold_time_out` => `setHoldTimeout()`
- `double_tap_time_out` => `setDoubleTapTimeout()`

Deprecating public member variables is tricky, but possible. I've created new,
private member variables, and added code to keep them in sync with the
deprecated public ones for now.

Also of note: The old `OneShot.inject()` function should now be unnecessary for
most purposes. It still works, but has a potential undesirable side effect. It
now needs to pick a physical keyswitch address to use for the injected OneShot
key, and that key will not be usable for its normal value until that OneShot key
is deactivated. Because of this, use of `inject()` is not strongly discouraged.
