include fixes

[rezso]

Add #include to prevent "invalid use of incomplete type 'class QUrl'" and "forward declaration of 'class QUrl'" compiler errors.

Thanks for sending that in!
Which compiler was giving you those errors by the way? I am using clang on FreeBSD here and have not had any issues, so I am just curious if there might be other little things like this that I am not seeing.

You're welcome :)
I used gcc 4.8.3 on linux, with qt4 4.8.6.
