Fail on startup if Thymeleaf template directory missing

Browse Source 
Better even than logging would be to fail fast? Surely it's a
mistake not to have any /templates if Thymeleaf is in use.
User can disable failfast by exlcuding thymeleaf configuration
or by providing their own ITemplateResolver.

Fixes gh-294
