Allow multiple custom layouts

This merges the "Layouts" option with the "Custom layout" option.
A custom layout becomes an item in the "Layouts" list among the other
layouts. It's possible to add several custom layouts.

Selecting the "Custom layout" item in the list opens a second dialog for
entering the layout description.

Layouts are serialized as JSON object and are decoded solely in the
LayoutsPreference class.
