Visual mode: when "Synch camera position" setting is enabled, and the cursor was outside of a sector when entering Visual mode, camera height is now adjusted based on nearest sector (previously the height was adjusted only when the cursor was inside of a sector).
"Auto-align textures X", "Auto-align textures X and Y" actions, UDMF: alignment source sidedef part's horizontal scale is now applied to all aligned sidedefs.

Game configurations: cosmetic changes in UDMF linedef flag names.
Updated ZDoom_DECORATE.cfg.
Fixed, Sectors mode, UDMF: surface cache was not updated after applying floor/ceiling brightness gradients.
Cosmetic, Sectors mode, UDMF: brightness gradient modes now have more descriptive names.

Draw Curve Mode: added settings panel.
Sectors mode: added "Make Door" button to the toolbar.

Interface: reorganized main menu. Hope it makes more sense now.
API: added General.Interface.AddModesButton() and General.Interface.AddModesMenu(), which can be used to add buttons to specific group in "Modes" toolbar and menu items to specific group in "Modes" menu, so actions, which behave like an editing mode, but are not part of one can be added there.
