* Add a port of the KWrite shell to C#

* There are some problems to be solved:
* Accessing some functionality requires qobject_cast<>'s
* How should mono KDE apps be installed? Should they be installed into the bin dir, or they should they be started from a C++ shell like Ruby KDE apps?

* Couldn't see how to convert this call:
QTextStream input(stdin, QIODevice::ReadOnly);

* The KUrl.List class needs more work to be usable with drag and drop
