Only show one status message dialog
|Reported by:||Zash||Owned by:|
Scrolling on the status triggers multiple "Write a status message" dialogs.
If you accidentally scroll a lot, you'll get a lot of status message dialogs, and since there's a countdown, it will send a bunch of <presence/> stanzas unless you cancel them.
Which isn't really that good.
Lock the status dropdown while the status message dialog is shown.
