Update kweb (#209)

* Update kweb to latest release
the fqdn needs to be part of kweb.cfg
make port 2015 explicit
fixes #208

* testing improvements
add git to build container
improve ci testing
add kopano-ical ports to setup


* no longer run kweb as root
now possible because of https://stash.kopano.io/projects/KGOL/repos/kweb/commits/fd5c7307db6ebfb8e326edfa98114be7c062f77d
may require to manually delete the kopano_web data volume since kweb user cannot read data from root user.
