[stockpile-docs] More info on F7 this.$route, etc

[devgeeks]

Perhaps we should have a bit more info on this.$route and its properties and methods the first time it gets introduced?

I think this is in /tutorials/stockpile/5-results-part1/ in the section for the computed property for the backLink.

1. In this new computed block, define a backLink property to determine which title to use on the link based on the route:

Maybe, a link to the F7-Vue Dynamic Route Matching docs? -- http://framework7.io/vue/navigation-router.html#dynamic-route-matching

@devgeeks I did actually have a green info block in the Renaming & Routing updates section in that same page where I link to that page and explain the dynamic routing a bit already but I will add some more notes about it on the backLink computed property too. It may not stand out enough.
