ktgk-qt3 - allows to use TDE dialogs in Gtk apps

This is an LD_PRELOAD hack that allows most GTK
applications to use Trinity's file dialogs when run under TDE.

It overrides the gtk file chooser functions to communicate
with this TDE module/application.

kgtk-qt3 is composed of the following pieces:

1. An application called kdialogd.
2. LD_PRELOAD libraries that are used to override the Gtk2 and TQt3 file dialogs.

Start an application using the following command to use the functionality:

    kgtk-wrapper <application>

kgtk-wrapper determines whether it is a Gtk2 or TQt3 application and then sets
the LD_PRELOAD environment variable to point to the approriate kgtk library.
When the application tries to open a file dialog, the kgtk library intercepts
this and asks kdialogd to open a file dialog instead.
There will only ever be one instance of kdialogd, and all apps communicate with the same
instance - and it terminates itself 30 seconds after the last Gtk/TQt app has
disconnected. This timeout can be changed by editing kdialogdrc and setting/changing

    [General]
    Timeout=10
