Better explanation of how connecting keys to other users work

[stemid]

At least 3 times now I've had users with the same issue. They're trying to connect a password key for another user. Which is common because you might not want to give out a password key password to other users just to connect it for them.

So they do this from the account Alice, connect the key to account Bob.

But since Alice does not have Bob's user password Alice can never complete the connection. All Alice can do is place a pending subkey in Bob's account. This is a siptrack specific feature.

So next time Bob logs in to Siptrack Bob gives his user password and with that user password is able to connect all the pending subkeys to his account.

The alternative is to have Bob give Alice his password. Or for Alice to give Bob the password for the password key she's trying to connect.

This needs to be made clear in the web gui because people are clearly not understanding the part with the pending subkeys.
