Some forum owners seem to have missed the detail about setting up an API key for the add-on to work, so we now also show a message at the top of the add-on page so they notice it at some point
The same summary of updateable addons that shows on the ACP index (if enabled) also shows on top of the add-ons page (by default on, can be disabled in options)
When clicking the "Get your API key here"-link in the addon options, it passes along your forum's boardUrl so you don't have to worry about getting the value right
