Reformat vectors.xml with xmllint --format for easier consistent XML formatting
Add cyclestreets snapshot-server information

This adds the snapshot-server information from http://www.cyclestreets.net/edit/editor/vectors.xml to the default vectors.xml

Unlike on cyclestreets.net the data is not loaded by default, but is available in the layers list.
Add the .DS_Store to the .gitignore.
