Patch file to fix the described issue

When doxygen needs to emit a warning on a function like

CSensorGroup::CSensorGroup(FPMLibrary::CSensorGroup% sg)
{
...
}

(attempting to generate something like:)

D:/Projects/ADS/Software/FCMS/dcl/FPM/FPMLibTestNet/HelperClasses.cpp(305): warning: no uniquely matching class member found for 
  CSensorGroup::CSensorGroup(FPMLibrary::CSensorGroup% sg)

it crashes. 

The reason is that an attempt is made to interpret the method header as format specifier for vfprintf() with no corresponding argument given (note that the declared parameter name starts with an "s"!)

I have attached a patch that fixes the issue (works for me, at least). Oh, and the patch addresses another issue, too: parseCommentAsText() may generate assertions in isspace() if an Utf8 character is encountered. Only "half" the character is passed on to isspace(), because result.at(i) returns just char, not an Utf8 character. That "half" character can be anything, though.
