feature/lookup: reduce coupling w/ lookup backends

Browse source 
You can now control exactly what lookup backends are used for the
various lookup commands (definition, references, online and file).

This allows you to disable (or add) backends by manipulating the default
value for these lists with add-hook or remove-hook:

* +lookup-definition-functions
* +lookup-references-functions
* +lookup-documentation-functions
* +lookup-file-functions
