OKTO2 RCS only stability assist works

[akshimassar]

Overall:

I have build new satellite using OKTO2. I also have RCS on it. When sattelite is on the orbit with only last stage, if I turn on RCS and SAS, then choose something except stability assist (e.g. prograde/retrograde), OKTO2 starts to wasting my monopropellant fuel. It seems that it tries to rotate prograde and maintain current orientation simultaneously. At previous stage (when additional fuel tank with another four RCS engines is attached), prograde SAS is working like simple stability assist.

Step to reproduce:

1. Take a vehicle to low orbit. I haven't tested it with other vehicles, than mine.

2. Enable RCS and SAS, select "prograde"

3. Detach second stage, if not already.

4. OKTO2 will start to make little burns in all directions.

Notes:

1. Removing RCS engines, that detaches at second stage does not changed anything.

2. Tested it in sandbox -- same result.

Tested it with reaction wheel. Worked as expected, but precision is not high (central dot is touching prograde circle, not pointing to it's center).

Yeah SAS is in need of re tuning
