Tweak timeouts regarding status notifications.

Send a <paused/> notification after 10 seconds, instead of 20.
Auto-remove a typing notification in the chat box after 20 secs instead of 10.

This is to avoid situations where the status notification gets
auto-removed while the typer keeps on typing without long enough breaks in
between for <pause/> states, thereby causing the recipient to not be aware that
they're still typing.
