Maintenancetool size cannot be changed after install

Maintenancetool size is written to maintenancetool.dat, there should be a possibility to change the maintenancetool size in update. This will come a bigger problem when we have 4.0 ready and start updating 3.2 maintenancetools to 4.0. As 4.0 has new side widget, it will require much more vertical space, otherwize the widgets doesn't fit properly
