[sha2017-orga] Update your teams insurable stuff

[Elger Jonker]

Hi Orga,

Some teams have tens of thousands of euro's worth of equipment on site. Yet this is not listed: we might have items that are out of scope but are part of the orga. To prevent questions at our insurance company, please list your items here. If there are special things that should not be on the wiki (?), contact attilla directly.
