For some reason, there were no errors/warnings when building on
Archlinux with gcc 4.7.1 and clang 3.1. I could reproduce them on an
Ubuntu VM though.

I've added -Wno-long-long to the build flags to silence these.

I spent some time researching this warning. Apparently it's
fixed in Qt 5, but forward declarations (as they are in Picmi) will not
work with QSharedPointers in Qt 4. I've decided to remove these forward
declarations for now.

The "'reverse' is not a member of 'std'" error has been fixed as well.

Building now completes without any errors or warnings on both the VM and
my main machine with clang and gcc. Compiling with kdegames trunk works
(once find_package(LibKDEGames) has been replaced with
find_package(KDEGames)). Please let me know if you still run into any
