evolution: rename unstable to orphan

Rename unstable to orphan in all external user-facing output. Only update
user-facing output for the moment, variables names, templates keyword and
potentially configuration would be done in later series.

The renaming is done according to
https://www.mercurial-scm.org/wiki/CEDVocabulary.
