Fixed, Sectors mode: fixed incorrect undo description when deleting sectors.
Internal: joined declaration and assignment of some more variables.
Fixed, Edit Selection mode: sector highlight was not updated when switching from Edit Selection to Sectors mode.

Fixed a typo in Hexen_things.cfg.
Draw Curve Mode: added settings panel.
Sectors mode: added "Make Door" button to the toolbar.
Swapped Side panel and Info panel z-order.
Interface: split toolbar into 3 separate toolbars. All toolbar buttons are now viewable at 1024x768.
Interface: grouped stuff in "Modes" menu a bit better.
Interface: added "Draw [stuff]" buttons to modes 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.
