Flash meetings UserPref is not needed.

[aubryio]

In the flash meeting gadget, userPrefs are not used but still declared. Since the new container will automatically display a form for it, it is better to remove it.

<UserPref name="fmurl" display_name="Meeting URL"/> should be removed and

// Get userprefs
// var prefs = new gadgets.Prefs();

is not needed either
