Removed sudo functionality, using umask instead.

This commit removes the functionality and necessity for
sudo calls between the openproject and git users.

As gitolite suggests, we now access the repositories through
the git group and a umask of 0770.

For more information on the gitolite config, see:
http://gitolite.com/gitolite/g2/rc.html

This commit also adds a few changes to the configuration:

 * delayed_job can be disabled through the config and is disabled by
default
 * The relative git storage dir has been replaced with an absolute path
setting for "Gitolite repositories base path".
 * Repository::Git no longer store the url as a relative path from the
git home directory, but only the relative path below the base_path
 * Added an output of the repository names in the config test

This commit adds the following organizational changes:

 * Introducing a changelog, even though no gem is released yet.
 * Adding hound/rubocop integration and extensive linting refactoring

Closes #9

+### Breaking Changes:
+
+** sudo requirement removed **
+
+The Requirement for sudo from `openproject` to `git` user has been replaced with direct read/write access through gitolite.rc's `$UMASK` directive. When upgrading, follow these steps:
+
+ 1. The ``$UMASK`` directive within the `gitolite.rc` must be changed to `0770` for any subsequent updates to the repositories
+ 2. The `<git home>/repositories` directory permissions must be extended to `770`.
+ 3. The openproject user must be added to the git user group.
