@todo
 
Finish complains' handling - what to do with received complains and how to respond?
Find out what to do with all "not used yet" opcodes
Correct errors sending (event/invite not found, invites exceeded, event already passed, permissions etc.)
Fix locked events to be displayed properly and response time shouldn't be shown for people that haven't respond yet
Copied events should probably have a new owner
