refs #9601
- refactor architecture of routing so you can define a channel
- a channel is a different way of looking at your posts (a view)
- a channel does not change the url of a resource
Example channel
```
routes:
/worldcup-2018-russia/:
controller: channel
filter: tag:football18
data: tag.football18
```
- added ability to redirect resources to a channel/static route
- support templates for channels
- ensure we still support static routes (e.g. /about/: home)
- ensure pagination + rss works out of the box
