Reflect new natnet options in control panel

[tblaha]

outdated config:

paparazzi/conf/userconf/tudelft/control_panel.xml

Lines 308 to 312 in 420a069

	<program name="NatNet3">
	<arg flag="-ac 9999" constant="@AC_ID"/>
	<arg flag="-o"/>
	<arg flag="-zf"/>
	</program>

Assuming Motive 2.x is used, then the new versions of natnet2ivy.py require the following config for setting North to the far side of the cyberzoo (see wiki). I would advocate for making this the default!

 <program name="NatNet3"> 
   <arg flag="-ac 9999" constant="@AC_ID"/> 
   <arg flag="--long-edge right"/>
   <arg flag="--x-side right"/>
   <arg flag="--ac-nose far"/>
 </program> 

Or the following for when true north is desired:

 <program name="NatNet3"> 
   <arg flag="-ac 9999" constant="@AC_ID"/> 
   <arg flag="--long-edge right"/>
   <arg flag="--x-angle -23.0"/>
   <arg flag="--ac-nose far"/>
 </program> 

When Motive 1.x is used, then we need to add the -o flag with <arg flag="-o"/>.
