  [modules] viewvideo: be nice to other threads

A simple attempt to slightly improve the scheduling, so that taking a shot 
doesn't block the rest so much.

This sets the computer vision thread nice level to 10, so that the main 
"thread" should get a little more.
It does in no way guarantee that something in the cv thread (like taking a pic) 
will not block the main functions like estimation, stabilization.

A better long term solution would probably be to run both the main 
program/thread and this module with the FIFO scheduler and give the cv thread a 
really low prio.

Not tested due to lack of hardware right now...
