Rebase on Panopoly and update to 1.6

[pirog]

We forked panopoly, but after discussions with snopek and populist we think there is great space to forge a mutually beneficial pathway forward. To that end we need to rebase hotsauce so that it is a panopoly subdistro again.

One issue that will need to be decided here is whether we dont include some panopoly features like search and pages, or if we attempt to override them using something like
https://github.com/kalamuna/panopoly_override

@andrewmallis and @reynoldsalec, can you help decide that we should do here?

This should get us back on Panopoly and updated to 1.6 version of everything; there may be some funk in the travis build, but it looks like it errors out when trying to kill the test server, not when actually installing Hotsauce. @labboy0276 may have further ideas.
