Subject: [PATCH] mouse: center horizontally using halign property

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.
