Add summary which asks the user to reboot on the navbar option
Settings: Don't hide home category if user has a settings capable launcher

By default the settings app hides the home category if it notices the user
has 1 launcher. Due to the ability to have settings per launcher, if the
user only has one launcher which happens to support settings, hiding this
category renders that feature useless.

So now we check if the user has < 2 launchers AND whether they support
a settings panel.

[1/2] Left handed navbar during landscape mode

This patch allows for the navbar to be moved to the left side of the
screen during landscape mode. Left handed people are more used to this
option.

This patch must go with another patch that changes framework/base
