Improving pattern linking to include View Alls

[EvanLovely]

Currently, the link variable for linking between patterns only supports linking to a single pattern, this adds the ability to link to the View Alls such as "Atoms > View All" or "Atoms > Forms > View All".

This has been added in PHP v2.8.5 from this PR.

This is an easy vote for me 😉 : 👍

From @bmuenzenmeyer :

Node supports patterns only. It would probably be pretty simple to implement, however. This would be a spec enhancement, IMO.

From @bradfrost :

I like this idea, especially keeping in mind the efforts to evolve PL into more of a style guide tool as well. Would be helpful to be able to link to a cluster of patterns.

A little after the fact... but I 👍
