- Corrected folder selection; reduced clicks required to select folders; improved text; added delete button. - Moved FolderChangeDialogTreeView to the same folder as the other TreeViews; - Added missing null checks to the MutliSelectTreeView and hid properties HScrollPos and VScrollPos from VS's designer (the former was initialised to zero every time the designer was updated, causing the treeview images to disappear).
