Redmine

It seems that the redmine_helper.py needs to be updated for more modern Mercurial versions. At least the rhsummary call used by Redmine::Scm::Adaptes::MercurialAdapter#summary seems to fail. I tested this with the current trunk at r24831.

hg -R tmp/test/mercurial_repository --encoding=utf-8 --config extensions.redminehelper=lib/redmine/scm/adapters/mercurial/redminehelper.py --config redminehelper.path_encoding= --config diff.git=false rhsummary

This outputs the following:
