From acacfda54016cbd4437d1ccaa609a52e9c1739d0 Mon Sep 17 00:00:00 2001
From: Adrian Kummerlaender

Subject: Added basic commit timeline aggregator implementation * another
 application based on StaticXSLT * git is instructed to export XML through a
 special log format definition * the commit messages are processed as Markdown
 * currently implemented result views are commits-by-repo and a paginated
 timeline of all commits in every repository * repositories to be read have to
 be defined in the `repositories.xml` file in the `00_content` level
