First draft of the policy

Policy is described in the README file. Currently includes only generic
and SuSE specific stuff. If somebody will join me, we can extend it ;-)
First version of the tools

Commiting several tools that may come handy while working with patches
following the policy described in the README. Following tools are
available:

 * apply-patches.sh    Takes file with the list of patches and applies
                       it using correct -p (taken from tag)
 * gettar.sh           Creates tarball containing only these patches,
                       that are in the 'series' file.
 * quilt-setup.sh      Creates necessary structures to allow working
                       with patches using quilt.
Less pretty but working

Removing some styling that made output prettier but actually broke the
functionality.
No more submodules, will merge stuff directly in
