YaST is now in Git
scr_switch_debugger.rb - Yast is not required at the target system

y2base binary and Yast packages might be missing so only glibc seems
to be really needed
install `perl-YAML-LibYAML` and `perl-bootloader` to the target system

instead of `yast2-installation`
Hide the steps from the installation workflow
adjusted the dialog layout
Adjusted workflow for future installer
implemented comments from review
mode selection removed, to be moved to boot menu
show release notes button

Conflicts:
	package/yast2-installation.changes
updated *.changes
Merge pull request #85 from yast/next_opensuse2

The new installer changes
