Replaced local Git log extraction with CGit ATOM feeds

* I just realized that repository specific commit feeds are already provided by both CGit and GitHub
** i.e. I made the mistake of not checking if my current system already provides the required functionality when I wanted to aggregate my commits and found this to be a use case for StaticXSLT
* feeds are fetched via `curl`
** this will be a local request in production
** the messages are still cleaned using `sed` and transformed into _XHTML_ using `peg-markdown`
* instead of reading a customized Git log output CommitLog now simply transforms CGit ATOM feeds using identity templates
** this requires ATOM namespace removal which is implemented in `utility/remove_namespace.xsl`
