Added FPS/UnrealEd-style right-mouse camera navigation to the camera view, with configurable movement keys, mouse look, modifier movement, Caps Lock speed scaling, and mouse-wheel zoom.

Added camera-view helper tools from the list, including reticle drawing, quick select during nav mode, teleport-to-looked-at-object, target lock/orbit mode, and entity/material info display.
Added nav-mode texture adjustment controls for position, scale, and rotation, and fixed the existing Alt texture-drag condition so Alt+Shift and Alt+Ctrl can actually trigger scale/rotate behavior.
Added widescreen support.
Changed up the menus and UI for build.
