cleanup: remove unnecessary (and potentially problematic) use of 'literal'
webhelpers.html.literal (kallithea.lib.helpers.literal) is only needed when
the passed string may contain HTML that needs to be interpreted literally.
It is unnecessary for plain strings.
Incorrect usage of literal can lead to XSS issues, via a malicious user
controlling data which will be rendered in other users' browsers. The data
could either be stored previously in the system or be part of a forged URL
the victim clicks on.
For example, when a user browses to a forged URL where a repository
changeset or branch name contains a javascript snippet, the snippet
was executed when printed on the page using 'literal'.
Remaining uses of 'literal' have been reviewed with no apparent problems
found.

=====================
Repository statistics
=====================
Kallithea has a *repository statistics* feature, disabled by default. When
enabled, the amount of commits per committer is visualized in a timeline. This
feature can be enabled using the ``Enable statistics`` checkbox on the
repository ``Settings`` page.
The statistics system makes heavy demands on the server resources, so
in order to keep a balance between usability and performance, statistics are
cached inside the database and gathered incrementally.
When Celery is disabled:
On each first visit to the summary page a set of 250 commits are parsed and
added to the statistics cache. This incremental gathering also happens on each
visit to the statistics page, until all commits are fetched.
Statistics are kept cached until additional commits are added to the
repository. In such a case Kallithea will only fetch the new commits when
updating its statistics cache.
When Celery is enabled:
On the first visit to the summary page, Kallithea will create tasks that will
execute on Celery workers. These tasks will gather all of the statistics until
all commits are parsed. Each task parses 250 commits, then launches a new
task.
