make binding manager destruct before command/variable manager to prevent unregistration from causing nasty surprises

my weird font renderer from Cfx (which currently is very Windows-specific, sadly Pango is weird to build so I didn't opt to change it to that) and a graphical console

mouse events, event listener lists, and primitive binding of mouse data to view angles in the temporary world viewer camera

a whole bunch of changes, including: key bindings and camera movement, changes in saving configuration, LODs for 'cleaner' rendering (though seemingly fairly flawed still), a minor amount of fixes

added EditorCameraControls class, an example of interpolated camera movement management + various changes

World/related: messy changes, a simpler frustum management thing, and ignoring LODs/alpha models - the latter as lack of depth sorting is all sorts of fun

SectorGrid: change _put_offset to 0 to properly handle frustum checks (the following commit contains both dirt I encountered while working on this and, sadly, a new frustum implementation as I thought calculation was wrong and aap went 'wtf' as well)

header files + random fixes; to use the world render test, use the "pgrid" command in the console; this populates the world grid with entities so they render

finished frustum math in WorldMath.h and added World rendering test with sector grid in World.cpp (thank you for giving an example rendering code!)

console variables: fix bad pointer treatment while casting std::string variables to a specific helper
