hooks: add mail-added hook

The mail-added hook runs whenever a message is added to a folder.
Note that the hook does not run when a new message is received (the
mail-received hook already covers that) but instead runs whenever aerc
itself adds a message to a folder, e.g. when moving or copying a
message.

Changelog-added: `mail-added` hook that triggers when a message is added
 to a folder.
