Version 6.15.4: "Summary" is required for default event types

[Xinrong Ding]

Today, our wiki migrate to a newer version: 6.15.4. When I open the Calender, I'm very disappointed. Some event types are self-explanatory. I really love the fact that in older versions, for default event types (such as "Leave") the summary is optional. Right now, it seems "Summary" is always required. It's such a redundancy.

This is an issue rather than a feature for me. Please look into it.
