comments: introduce lazy join of ChangesetStatus on ChangesetComment
99% of all uses of ChangesetComment will also need the optional corresponding
ChangesetStatus (if any) on the status_change relationship. Fetching it on
demand gives a lot of roundtrips and might be slow ... but adding explicit bulk
queries everywhere do not seem feasible. Adding lazy=joined in the data model
seems like the best solution.
Loading a pull request with 10 comments on a slow repo goes from 3.5 s to
2.7 s.

=============================================
working with Kallithea and mercurial subrepos
=============================================
example usage of Subrepos with Kallithea::
## init a simple repo
hg init repo1
cd repo1
echo "file1" > file1
hg add file1
hg ci --message "initial file 1"
#clone subrepo we want to add
hg clone http://rc.local/subrepo
## use path like url to existing repo in Kallithea
echo "subrepo = http://rc.local/subrepo" > .hgsub
hg add .hgsub
hg ci --message "added remote subrepo"
In file list of repo1 you will see a connected subrepo at revision it was
during cloning.
Clicking in subrepos link should send you to proper repository in Kallithea
cloning repo1 will also clone attached subrepository.
Next we can edit the subrepo data, and push back to Kallithea. This will update
both of repositories.
