Hi Herbert,

thanks for the feedback and your patch. I've commited your changes and some 
additions from me.

Ok, I'll drop to what gnucash requires.

Currently, the only 4.5.0-feature was the QSharedPointer, which I've removed 
again because it was unnecessary and not as powerful as I thought. However, I 
would like to stick to 4.5.0 as a requirement because it is already a year old 
and (more importantly) there isn't any easy way preventing to add 4.5-only 
features when developing with 4.5.x, which introduces unnecessary trouble.

I've added this as well. Thanks for pointing this out.

Also thanks for the suggestion with the extern "C" - I've changed this in all 
c++ files as well.
