Description of Problem:
Arrow keys do not work for scrolling the release notes in the graphical installer.
Instead, the focus jumps between buttons.
This can be fixed in the gtk2 based installer which is scheduled for future
deployment. Till then it is quite hard to fix.
(Note that the help text on the left side doesn't scroll with arrows either.)
Page Up and Page Down will do this now.
The keyboard navigation is very sane on the release notes window now.
Time tracking values updated
