Add option to show only the unique prefix of tab names

When the set of tabs used fluctuate, the memory of which number
belongs to which chat becomes difficult to work with. Non-numbers
can be used to navigate tabs with `/win`, however, it is difficult
to know which letters are required to select a certain tab.

This option introduces a display mode for tab names where only the
unique prefix of the tab name is shown, saving space and providing
with a minimal string which can be used with `/win`.

If you want to show the tab name in the bottom Tab bar, set this to ``true``.
unique_prefix_tab_names
**Default value:** ``false``
If this and :term:`show_tab_names` is set to true, only the shortest
unique prefix of each tab name is shown instead of the full name. This
can declutter the interface in an instance with many tabs shown in the
interface, while not having to use numbers (which may change completely due to reordering).
Takes precedence over `use_tab_nicks`.
