FFE: add xinput-calibrator to natty

[Timo Aaltonen]

The evdev driver needs a calibrator for touchscreens, since -evtouch is obsolete and the calibrator that was shipped with it doesn't work with evdev.

From [1]:

"A generic touchscreen calibration program for X.Org.

xinput_calibrator is created to fill the gap of touchscreen calibration software, featuring:

    works for any standard Xorg touchscreen driver (uses XInput protocol)
    mis-click detection (prevents bogus calibration)
    dynamically recalibrates the evdev driver
    outputs the calibration as xorg.conf.d snippet or HAL policy file
    and more"

We need it, because there is no calibrator left after evtouch is removed.

The author has packaged it for several distributions, including Debian and Ubuntu, and the package has gone through Debian Mentor review [2] (most of which have been fixed since). The packaging is currently at the same place as the upstream code [3], but will move got git.debian.org under pkg-xorg team maintenance.

I'll attach the latest source version tomorrow, in the meantime this should work:

+1. I've played with this tool a year ago on ubuntu. It could benefit
from some integration work but even on its own it provides the info
users need to get their touch devices configured.

Adding this new package is no risk, and it fills a gap of previously available functionality, so approved. Thanks!

Thanks, I've uploaded the package, waiting in the NEW queue now.
