Error checks: added "Check unused textures" option. Replaced MissingTexture3D and UnknownTexture3D. Sectors mode: restored "Lower/Raise Floor/Ceiling by 8 mp" actions. Visual mode: in some cases sidedefs were rendered as selected when they were not. Existing linedefs were not split while drawing new lines in some cases. Texture and height overrides were not applied correctly in some cases. Preferences form: "Ctrl+Alt+ScrollUp" and "Ctrl+Alt+ScrollDown" dropdown items were setting the shortcut to "Ctrl+Shift+ScrollUp" and "Ctrl+Shift+ScrollDown".
