[TASK] Add FAL support to image info view helpers

[bjo3rnf]

As requested in #619

[NamelessCoder]

Please refactor to add two methods getInfoByReferenceUid and getInfoByUid and turn the current getInfo method into a wrapper which calls either of these methods according to ViewHelper parameters.

This will help us create tests for the code.

Sure thing, force pushed. The other VHs provide the argument src, this one uses path. Should we unify them knowing it is a BC break?

I vote yes to that - but the change must be recorded as breaking change for the 2.0 release note.

Björn would you mind cropping off the last commit and making that as a second PR once this one is merged?

[bjo3rnf]

Sure thing. There you go.

Ready for seconds ;)
