When a touchpad supports it. When the option is set, it will
automatically disable two-finger scrolling.
The scrolling method used by each individual touchpad is implemented in
mutter, not here.

The Mouse & Touchpad panel has a horizontally centered
list, which is centered pixel-counting the list width and
hardcoded margins.
This approach has various issues. It resizes the window
needlessly when e.g. the font changes the size, dpi or
family. This is specially visible when dealing with low
resolution screens, where the hardcoded margins are too
much to fit a 720x480 screen with the Large Font accessibility
setting on.
Fix that by removing the margins and setting the horizontal
alignment of the list to center. Since the list itself doesn't
expand to fill the available space, there won't be any user-
visible changes except that the panel is now able to scale
down.

Instead of using only hardcoded height requests, it's better
if we give more flexibility for the content to grow up to
a certain amount of pixels.
Also, this patch slightly reduces the maximum size by 20px, so
that in the tested scenario (Adwaita with Large Font settings on)
the panel is still able to size down.

The GtkBox>GtkListBoxRow>GtkListBox hierarchy is unnecessary, also
remove the GtkSeparator from the GtkListBox and move it into the GtkBox,
so the width matches that of the GtkListBox (it missed 2px on either
side before).

The two-finger scroll method will be enabled in all cases
(see bgo#759304). When a touchpad without two-finger scrolling
support but with edge scrolling support is available, show the
switch.
Also bump the required gsettings-desktop-schemas version for
the new key.

Since the first entry in the Touchpad section causes the sensitive
of the items below to change, those items are in a diferent ListBox.
To make it look like it is all the same ListBox, we arbitrarily add
a separator between the first item and the items below.

Most peripherals settings have been moved to
gsettings-desktop-schemas.
There are some semantic differences:
* pointer and touchpad speed is now a single value in the [-1..1]
range (from "unaccelerated" to "fast"). A value of 0 is the default;
* touchpad enabled is now an enum which can be enabled, disabled or
disabled-on-external-mouse. This patch keeps the same UI so the last
value is the same as disabled in the UI and can't be set for now;
* disable while typing is now always enabled so the checkbox has been
removed;
* horizontal scrolling is always enabled when two finger scroll is
disabled. It wasn't in the UI but we no longer need to set it since
it doesn't exist anymore.

...to "Natural scrolling". The previous name was a little bit
disgusting, and people didn't understand its purpose. Using the
same name as OSX means that people will either know it, or be less
afraid of testing it.

The Acceleration mnemonics were conflicting with the 'All Settings'
mnemonic, which can easily be avoided by moving the mnemonic to 'c'.
Also, the mnemonic widgets for the scale labeles on the touchpad
page were pointing at the widgets on the mouse page (copy-paste error)
and thus did not work.
