wacom: drop Orientation from the Tuhi daemon

This isn't something we need in the daemon, it depends too much on what the
client expects so let the client save this data and handle the rotation
accordingly.

Note that the sensor in Sparks and Slates is in landscape format, i.e. every
picture is 90 deg rotated from what you'd expect.

Fixes #33 (wontfix)
