Added, all drawing modes: added "Continuous drawing" option (available in the top mode menu / Draw Grid panel for the Draw Grid mode). When enabled, drawing mode will not be switched to previously active mode after finishing drawing a shape.
Fixed, general interlace: in some cases "Show Editable Vertices in Visual Mode" top toolbar button showed up when using Doom/Hexen map formats.
Fixed(?), Classic modes: probably fixed an rare issue when map element dragging was not starting when supposed to.
