Installing multiple addons at once ignores addon requirements, leading to unexpected install/upgrade failures

If Addon A depends on Addon B, but users select addon A and addon B zip files (in that order); this will cause the install/upgrade to fail despite them providing all the required addons. If they manage to select addon B and addon A in the upload dialog then install/upgrade will works without errors.

This results in a deeply confusion experience where the order of selecting files in the file upload dialog matters.
 
Clearly, there should be some way to alert the user of such dependencies.

Also, XF should perhaps allow installation of A, but leave it disabled until B is installed too. It wouldn't be that hard to develop this function, either. XF provides the framework and the developer uses it to develop dependency-safe add-ons.

What if the installation of addon A requires dependencies within addon B?
 
Not a problem, just put it into the XF installation protocol to show a warning and prevent the installation. On top of that, the add-on could optionally contain a link to download the dependent add-on.
 
It isn't that hard to sort add-on by their requirements and ensure they are installed in the right order.

The code needs to visit each addon's addon.json to verify requirements anyway, so this is just adding a sort step between extracting addon.json and checking requirements.
