Add a /current route that we can use in various places

[acorncom]

At times we need the ability to link to "the most current" version of api docs (see #184 for an example). We need to add a /current route to this Ember app that will display the most current version of the api docs.

It could be implemented by sorting projectVersions with something like https://github.com/ragingwind/semver-sort. But maybe it would be better to sort it already in jsonapi-docs project. It would probably be more efficient.

[sivakumar-kailasam]

we already have an array of sorted versions based on semver. We just need to handle /ember/current/ in the route load the latest one 😄

[MartinMalinda]

It does not seem to be sorted here: https://ead-sk.global.ssl.fastly.net/rev-index/ember.json. Maybe I am looking at a wrong place?

[sivakumar-kailasam]

Oh its done part of the app in that route's controller

[MartinMalinda]

I see, that's great then. I will use that :). Probably will have to move it to the model though.

Would be cool instead of or in addition to /current, to have /release, /lts, and maybe eventually /beta and /canary

[Gaurav0]

Hopefully /current and /release are the same.

[toddjordan]

correct, though I feel like "release" would be clearer to what "current" means. Current could mean canary or beta or lts as well.

Maybe we should reopen this? I will revisit this once the route structure refactor is merged.
