fix: enhancement to history command output and % template fix.
Rather than using the key field, use the label field for descriptions.
Call cls.labelprop(default_to_id=True) so it returns id rather than
the first sorted property name.
If labelprop() returns 'id' or 'title', we return nothing. 'id' means
there is no label set and no properties named 'name' or 'title'. So
have the caller do whatever it wants (prepend classname for example)
when there is no human readable name. This prevents %(name)s%(key)s
from producing: 23(23).
Also don't accept the 'title' property. Titles can be too
long. Arguably we could: '%(name)20s' to limit the title
length. However without ellipses or something truncating the title
might be confusing. So again pretend there is no human readable name.
