Ability make Vacay Calendar View Only for other users

[SteveKrupa]

Absolutely love the calendar setup (especially the company holiday setup), would love to be able to lock down and allow people to see my vacay calendar, but not have the ability to edit it.

Some ideas:

• share only option - no editing just looking
• allow someone to edit, but I approve/confirm what they change on my calendar

Really love this project, great work!
