Adjust input boxes to fit the screen better on mobile, and to use
consistent sizes throughout the site (no ad-hoc overrides to make
certain input boxes a bit bigger in random places).
On desktop, this makes most input boxes a bit taller and narrower. On
mobile, it makes input boxes the full width of the screen.
This most notably affects the tag edit box, the comment and forum
post box, the wiki page edit box, and the commentary box.
Track when an API key was last used, which IP address last used it, and
how many times it's been used overall.
This is so you can tell when an API key was last used, so you know if
the key is safe to delete, and so you can tell if an unrecognized IP has
used your key.
Add the ability to restrict API keys so that they can only be used with
certain IP addresses or certain API endpoints.
Restricting your key is useful to limit damage in case it gets leaked or
stolen. For example, if your key is on a remote server and it gets
hacked, or if you accidentally check-in your key to Github.
Restricting your key's API permissions is useful if a third-party app or
script wants your key, but you don't want to give full access to your
account.
If you're an app or userscript developer, and your app needs an API key
from the user, you should only request a key with the minimum
permissions needed by your app.
If you have a privileged account, and you have scripts running under
your account, you are highly encouraged to restrict your key to limit
damage in case your key gets leaked or stolen.
* Add an explanation of what an API key is and how to use it.
* Make it possible for the site owner to view all API keys.
* Remove the requirement to re-enter your password before you can view
your API key (to be reworked).
* Move the API key controller from maintenance/user/api_keys_controller.rb
to a top level controller.
