[fpc-pascal] GTK2 Lazarus Project, but I want QT.

[Felipe Monteiro de Carvalho]

I just added here support for Qt 4.2

Only some ifdefs to switch between qt4 and the qt42 unit were necessary.

You can turn the Qt 4.2 mode using the define USE_QT_4_2. commited on
revision 11352

Unfortunately it didn't work. Compiles and links fine, but crashes at
startup. Not sure what is wrong, however. Anyway, I need to go now,
I'll be back in manyy hours or in the weekend.

[felipe at felipe test]$ ./projecttest
Gleitkomma-Ausnahme

Lol! Maybe it wasn't a good idea to change my linux to german =) I
have no idea what this means ... only that Ausnahme=exception

Possibilities:
1 - I need to upgrade my Qt 4.2.2 to 4.2.3
2 - The quick bindings that Dean made are broken.

Backtrace just for the record:

In case anyone is wondering by this bizarre error, the app does work
fine with Gtk 2
