Reduce alias use…

These commands do the same thing: list-tracking, list-trackees, & list-following, clutter up the help / cmd list, and aren’t at first glance the same command.

`keybase` and the site use ‘track’ as the verb, so just list-trackees and list-trackers (in future) would seem suitable. Or simply `keybase trackees` `keybase trackers`

{same thoughts for trck, vrfy, conf, gen … a bash completion helper should minimise typing without making commands illegible. Unless you want to keep these and remove the long forms}

Start by reviewing the `list-tracking`, `list-trackees`, and `list-following` commands, along with the proposed `trck`, `vrfy`, `conf`, and `gen` aliases. Inspect the CLI help and bash completion behavior to understand how aliases are exposed. Done means the command names and aliases have a consistent, legible policy and the help/completion listings no longer create the stated clutter.
