[REQ] User script for regular sonar checks

<EDIT>
The script is ready and works well, check the thread further.
</EDIT>



I can't script. I just can't. I would love to have this script though:

1. Every [period] if not submerged, dive to 20 m depth.
2. When at 18m depth, switch engines off.
3. Wait 2 minutes.
3a OPTIONAL, if possible: if sonar guy detects anything, do something (like 'play a sound', 'go to TC1')
4. Surface.
5. When on surface, switch engines on for speed of X.

What you think? Anybody capable and willing to make it?
