xF2 Add-on Addon Update Notifier 1.1.8 Patch Level 1 1.1.8 Patch Level 1

• Some add-ons (unclear which, but only seems to have affected some forums) apparently have some magical addon.json format that broke the collection of add-ons for checking.
• This fixed version checks that the specific addon.json values are strings (as they should be) before trying to use them, to ensure that it doesn't crash.

Show buttons for download/changelog in the notice on top of the add-ons page:

Basically a fix to hide the "update available" info and buttons for add-ons that are disabled.

Since XoN add-ons nowadays use their own magical versioning system, we managed to introduce a bug with the last release, which fixed add-ons using the "90-hack" to be picked up correctly.

This bug made various XoN add-ons show up as having an update, even if the latest one was already installed.

• By default (since this update) the download button has been set to download directly from xenforo.com if possible. This release adds the option to prefer downloading from developer's own site if it exists.

Don't show version/download/changelog info in the "Upgradeable" box.
(When FTP uploading zip archive with new version)

Since it was requested by a few customers to allow more add-ons, we decided to add 2 new tiers..

If you currently have e.g. 60 extra add-ons and choose to upgrade to 120 extra, the remaining days on your current license will be prorated, e.g. 50 days remaining on license @ 60 extra add-ons becomes 25 days remainings @ 120 add-ons + 1 year from that date.

• Some phrases had been added during development when we tested the 90-prefix in versioning.
• This release resets them to be on version 1010391 rather than previous wrong value of 901000070

• Show info if your forum is blocking the callback about new updates
  • This message can be disabled in the add-on options

• AUN is not counted when showing the used amount add-ons from the limit
  • The backend already had this, but frontend didn't correctly indicate it.
• Exclude legacy add-ons, thanks @SeToY
  • Not checked
  • Not counting toward limit
  • Not showing any indicators
• Added a missing ? to phrase, thanks @Nicolas FR
