Phaedrus Leeds 600e18567c Add a vim modeline and .editorconfig 
To make indentation work with less effort. The modeline was copied from
libostree with minor modification and the .editorconfig from GLib.

The advantage of having both a modeline and an editorconfig is we can
work out of the box on more editor setups, and the modeline allows us to
specify the style with a lot more fine grained control.
