rework current front facing proxy (#40)

* replace previous caddy construct with kopano kweb
* add kweb to makefile
* greatly simplifies setup, if user wants to tweak config of kweb he could do so in git and make a local build. Fixes #22 
* ping kweb version
* update readme
* remove build argument from docker-compose for web and ldap-demo
* fix certificate handling in kweb. fixes #38
