Fix incorrect declaration of constant member function.
Remove unnecessary 'inline' keywords.

A function defined within a class definition is an inline function.
Fix signature of ChStreamOutBinary insertion operator for char*.

The only operator overload needed is for 'const char*'.
If the only overload provided is for 'char*', then passing a const char* would end up using the bool overload (this was the meaning of the warning issued when compiling ChObject::StreamOUT).
