This is some very initial work that has been done for updating the API tokens UI

for our move to API tokens v2. The changes that I planned to complete are:

- Nicely display tokens that are 255 characters long.

- Show when tokens were last used.

- Show when tokens will expire or if they are expired.

- Allow users to set an expiry date when generating a token (by choosing typical

  options from a drop-down list (7 days, 30 days, etc) or set a custom date

  through a date picker widget).

- Show when tokens are invalidated.

- Maybe allow users to invalidate their own tokens from the UI.
