first commit on feature #115.

adds user table. posts now have a owner attribute that identifies
the user that created or reposted the post.

a testuser is created on initdb, all posts are attributed to it
until proper session management is in place.
friends now have a owner attribute.

it specifies the instance user that added them.
changes template handling and data model

up until now, every few did call the ttemplate rendering on itself, this
clearly is a bad idea because every time it is called, a new context
for jinja has to be created.
The template handling has been moved to wurstgulasch.py, which
simplifies the handling a bit.
For every view there now has to be a template with by the name of
    < view name >.htmljinja
If a view has nothing to return it needs to return an empty dictionary.

Also, the data model has been changed, friends are now user-specific
