Bump to Play 2.3.6, akka 2.3.6 and related

What I did here was bump to play 2.3.6 and then fix templates and fix activator until they were all in sync with a consistent offline cache. So this (combined with the template patches) was a minimum changeset to get to Play 2.3.6.

1.0.5 was specified by one of the templates I think, here I filled in the missing dep rather than going to look for latest. Do you need 1.0.7? It isn't a big deal I just have to bump to 1.0.7, re-run offlineTests, and see which template is wanting 1.0.5 and fix that template.

Comprehensively bumping all the versions in this file would take more time - I would have to look up the latest for each, and then cycle offlineTests with template fixes and potentially releases of other packages until the whole thing resolves. I didn't want to open that can of worms here because it could easily take a couple of days, even if there are no surprise bugs or complications.

If there are particular version bumps you would like to see it's probably a lot quicker to bump a couple specific things than to comprehensively update everything.
