Add a vim-modeline for the config example.

This sets the correct modes for vim when editing the configfile. This is
especially needed, as YAML uses indentation for structures.

Options set:
- filetype to YAML (else 'conf' is infered)
- set the number of spaces a tab is to 2
- expandtab -- do not insert \t but spaces
