Feat: add enabled attribute for the configuration of UiElements

[jacquesbh]

Hey! Thank you for this!

It's a great idea.

I would like to discuss it a bit.

I think disabling a UI Element leads to many points:

• a disabled element should not be proposed in available UI Elements
• a disabled element should be parsed in admin, always, with a small warning indicating that the element is disabled, can be edited, but cannot be added anymore.
• a disabled element should not be displayed in front

In other words, if you disable an element a year later, it could be present in many contents. So we don't want to display it anymore (since it's disabled) but we don't want either to remove it from the old contents since I always say "do not remove data" (as a developer).

So, we need to continue this PR in order to make it work properly I think.

What do you think?

@jacquesbh it was a first draft, but what you propose seems to me very good.

I'm watching this as soon as I can this week.
