Bring back Camera widget option for tablets

Starting from ~2014-01-29, Camera widget is also shown on tablets.
That's actually a good thing, so let's bring back the option to
make it configurable.

[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

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.
