Event Dashboard Info Box: Enhance it and fix issues

[mariobehling]

The event dashboard needs some enhancements and fixes. Please change as follows:

• Delete row "number of revisions"
• Depending on event show
  • either "Location" - and show the address
  • "Online Event" - and show the links
  • "Location: To be announced" or
  • show both "Location" and "Online Event" rows for "Mixed Events" including data
• Fix social media names to start with a capital, e.g. Twitter instead of twitter
  • fix it on the infobox
  • also fix it on the public event page (which is the same cause) compare to https://eventyay.com/e/0917096d
• Change "External Event URL" to "Event Site"
