metadata: make linkresolver an actual object

Browse source 
Previously this was magically capturing the apps dict when passing it around as a
function. This also moved the code to the metadata module.

Add a test doing read_metadata where the linkresolver is used. This
happens when the apps we read have a [[app.id]] link to another app.
