* - Enable use of override for session timeout. This is more useful than having to hard-code and rebuild the code for the previous 4 hour limit. Just set environmental variable and start the app.

- Fixes bug in Captcha code by introducing new landing page. This is not a new go template, it's a separate HTML file because SRP - single reponsibility principle. Happy for this to be refacted after merging commit.
- Fix for including Docker 1.12 override has been removed for later PR.
* Merge
* Reinstate 'material' JS include'
* https for JS includes
