[cv6] Custom Field Extension 1.1.0 RC3

With this brand new AddOn you can add new types of custom fields:

• Image
  The User can upload one or multiple images (XenForo Attachment System is used for this)
• Combo Box
  The Combo Box combines a Text box and a Simple Drop Down Box. You can change settings for both elements as usual and define the order of both.

New Options:

• The number files now has a step value
• You can specify a placeholder

All other: See images!

Supports also Resource Manager.
You can add very simple with this add on a tab with screenshots.

Even if this Version has the RC label, please not use this in production and create a bckup first!

This addon changes some core templates on a heavy base. I tried to do this very carefully, but it can interfere with other addons that modified attachment behavior. If you encoutner issues with other addons, please let me know and I will take a look.

It works in default Style. Please drop me a conversation if it not works in your modified style.

Core AddOn which from now on, (nearly) all AddOns will require.
