Error messages not always helpful

Summary: Went to https://querki.net/u/jducoeur/period-games/#!Vendor and got the error "There is no Thing named "Display Name" -- might be a typo? If you want to use that name as a Tag, put it in backticks." While this might be helpful to the owner of the space, it is decidedly unhelpful to a third party who might encounter it. I suggest error messages start with some basic 'a thing went wrong' text, maybe with a collapsed div showing the technical elements of the error. For bonus points, there should be a button to report the issue to the space owner which opens a contact form and when the report form is sent also includes the technical information and the page where it happened.
