When adding a scheduled BigBlueButton call into the Moodle calendar, this currently happens:

1) The event name is "XXX is scheduled for" ... which is redundant, not grammatical and probably breaks even worse in other languages

FIX: Just use XXX for the event name.

2) The event is entered as zero minutes long, even though I had a CLOSE time in the settings.

FIX: use both the OPEN time and the CLOSE time to set a duration in the event.
