Allow overriding of SNI icons

Browse source 
This adds a config option to override the name of the icons displayed.
This also removes the frankenstein monster of the icon location
querying, which was a giant mess and not even remotely close to being
compliant with the XDG spec. Instead we use the much simpler Gtk API
which has the added benefit of properly supporting themes.

The SNI filter also now work for items without a set tooltip (e.g. steam).
For these items the object name is matched instead.

Implements https://github.com/scorpion-26/gBar/issues/63
