Changed a way of 'test' work - now it's all in one big command

Done by reading "From Bash to Z Shell"
Added systemd timesyncd service (which requires networkd) to control
time like with NTP
Added cached software packages (cached install)
Temporary commit (for reviewing). MESSY. Will be deleted
Working Local installation of official binaries

Aur is not working because it's just folder with cache now, not local
repository. I will add local repository feature as soon as I'll discover
how to install software from [aur] instead of [local] if local is not
working
Be very careful.
Localinstall turned off (not enough skills to do it right)
Fixed lastest errors after fresh install.
Added libnotify (need it now)
Cosmetical changes based on my new shell skills
Added okular configuration backup
Changed ownerwhip of /etc/.dotfiles/.git after installation
Added irssi again
Added irssiscreen service to autoenable during install
Merge branch 'master' into notebook
