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`.

This reflects reality, despite the default values of the code.
We still need a better solution (singleton?).

we MAM now

don’t ask, don’t tell

Tabnames should be treated as opaque strings.

This specific fix prevents tabname (JID) to be compared with invalid
stringly-typed JIDs. JID's __eq__ method used to (after
poezio/slixmpp@47968963

) try and convert anything into JIDs. This has
been fixed and now properly returns NotImplemented.

It looks *modern*!

Since this is a privacy sensitive action, a short message is now

This reverts commit bde9b311.

This also switches to pathlib.Path instead of os.path for path
manipulation.

This prevents bugs in some terminals.
