Michal Čihař - Sample config after long wishes

Sample config after long wishes

Since we've removed default configuration from top level directory, people often copied config.default.lib.php what was not something we wanted.

Last week I finally decided to make some sample config which will be placed in top level directory, so that people can easily start from it and add further options after reading documentation or wiki. Let's see if it will prevent people from copying defaults in upcoming release.
