Why not PROPFIND too every 5 minutes ?

[georgehrke]

Note to myself - there is one more issue:

• click existing event to edit it
• try to drag it -> won't work because its locked
• wait for refresh to kick in
• dragging now suddenly works -> that's not how it's supposed to be

Possible solution:

• take fcEvent that's supposed to be edited
• remove it from calendar
• use renderEvent with stick=true to render as individual event

@tcitworld PROPFIND takes twice the requests.

Also when it comes to refreshing calendars, it'd like to keep the original object from the initial request and not replace it every 30 seconds ^^

Rebased.

Needs a proper implementation in the vue app + cdav-library
