summary: add evolution "troubles" information to parents header lines

Extend labels of the `parent: ` line according to what `hg log` displays when
coming from changeset_printer. This would make this line appear the same in
log and summary with custom colors in particular.

Extend that line with "troubles" information in parentheses, when the parent
is troubled.
