Selectable header content

[bartbutenaers]

Description

This PR replaces the following checkbox in the ui-base:

By this dropdown:

With the following result:

The header is automatically updated after a deploy.
And the old checkbox values are migrated to the new "page" or "none" values.

Remarks:

• I had added a width of 70% to the dropdowns (like I normally do) to make them as long as the other input fields, so that the content of the longest option label fits into the dropdown (as in the above screenshot). But then the dropdowns jumped to the next line when I opened my config screen. So I have removed that again...
• I have not updated the documentation (i.e. md and info panel) because it looks to me that those settings are not described yet...

A great addition. I've also made the browser tab title align with the selection too, which defaults back to the page name in instances where the selection is "None" (as we already need a title in the browser tab)
