saveTotalSCode with +showAnnotations generates bad file

[adrpo]

Just try omc +showAnnotations on this:

loadModel(Modelica); getErrorString();
saveTotalSCode(Modelica.Fluid.Examples.Tanks.ThreeTanks); getErrorString();

There are several errors:

1. the comment in the last class is placed badly
2. the quotes inside comments are not escaped in some cases

Also, while i'm at it: having top class M and doing saveTotalSCode on it will get you a new top class M extending from the top M which is invalid
Modelica code. We could check if name exists in the top scope and generate an unique one if so.

Fixed in r22808.
