Fix visual issues with long labels in the open project dialog

The following issues are fixed:
 * Printer/Quality/Material names will be wrapped if they are too long
 * The width of the window is determined based on the content of the dialog.
	With that there will not longer be overlap between the dialog content and the buttons.
