Implemented Add display positions for AMS description field

[Andro]

Currently, the AMS description field is used for SEO purposes only.

It would be great if we can have some positions within the article to display the description field content.

Some positions for example:
- Display description in header
- Display description above article

Thanks

This was funded by a long time AMS Premium license holder.

I've added 2 new options that allow admins to enable displaying the Article Description in the Header area and or above the Article (similar to how Showcase does it).



And here you can see where the two display options are.

Note: I'll leave output customization styling up to individual admins.
