Use the more traditional '.dist' extension for configuration templates
that are part of the MapOSMatic distribution. Update the installation
instructions accordingly.
Includes some style fixes in the INSTALL and template files, as well as
a fix to the wrapper script to correctly allow for an undefined log
location (defaults to stderr).

This is the first step of the rewrite of the MapOSMatic rendering
daemon. The long-term objective is to get a more flexible rendering
daemon that would support the rendering of several jobs in parallel, and
with an overall more Python-y and maintainable code.
This first shot brings a completely new, simpler MapOSMatic daemon with
the same level of functionality as the previous daemon in terms of
serial rendering of the job queue. Three major changes happen here:
1. the bash-based wrapper script has been removed, in favor of a more
clever Python wrapper. Cleaner, and more importantly more portable.
The wrapper still needs a bit of configuration, and after the
config.py-template has been tweaked into a valid config.py file,
the daemon can be started by:
.../scripts/wrapper.py scripts/daemon.py
2. the externalization of the rendering routine into a 'render'
module. This module does not access the database - only the daemon
does. The sole purpose of the render module is to encapsulate the
rendering process and its errors+exceptions handling.
It can also be used as a standalone, job-ID-based renderer:
.../scripts/wrapper.py scripts/render.py <jobid>
3. the cleanup mechanism now runs in a separate thread, in the
background.
