Scoring info in footer
scoring values in footer not hardcoded anymore
use File.open instead of File.write

I'm using Ruby 1.9.2. Apparently, it doesn't have the File.write method.
change title and map link (-> Paderborn)
only 3 retries in cronupdater.rb because we update more often

My changes may also fix a bug. I think the script didn't behave
correctly, if the maximum retry count is reached. I didn't test
it though, so I cannot be sure ;-)
rename settings.rb to settings.rb.example and ignore settings.rb
add settings.rb for Paderborn
ignore dot files
move TITLE and GRAPHLINK to settings.rb
move password into dedicated file
