Fixed FirstPersonControls not handling resizing. Fixed some more examples not handling resizing / zero sized window.

See #2062.

This is tiring :S

Sorry @dmenne and @mrdoob, unfortunately this was causing more pains than it solved (#1986).

This interfered with very common use patterns on vanilla browser settings (e.g. page reloading or opening of console) while it helped just with a specific customized browser issue.

And it doesn't help to just call preventDefault on "consumed" events, as individual keys can be still part of multi-key hotkey combos (e.g. "R" is used both in FlyControls and "ctrl+R").

false = up is up
true = down is up

Lots of code got cleaner with seconds, seems we used them before all around.

Also changed examples that didn't need deltas to simple Date.now() plus some more examples cleaning, trying to get rid of obsolescence warnings.

Changed few examples to use this.

This will take a while to make work again... probably needs some cleaning and refactoring...

Removed QuakeCamera.

Modifying FirstPersonCamera, FlyCamera, and PathCamera to fully support their `domElement` parameter

Corresponding keys:
 - R up
 - F down

Add QuakeCamera alias for backwards compatibility.

Fleshed out RollCamera: refactored code out of example, add more keyboard controls, API and made it framerate independent.

Also changed autoForward in QuakeCamera not to interfere with backwards direction.

Tweaked a bit minecraft AO demo, using extra power for more cubes.

WebGLRenderer antialias is off by default (considering Firefox doesn't support it...)
Formatting clean up here and there

Added Q-button to Quake Camera to freeze update (good to have when debugging stuff so camera go away)

DragToLook was weird, instead activeLook can be now used for simple switching on/off of mouse look around.

PathCamera automatically follows path passing through waypoints (interpolated via Catmull-Rom spline). View angles can be constrained and controlled by mouse.

Work in progress, there are still some issued to be solved (constant movement speed, broken automatic update, broken frustum culling).

Also half-baked QuakeCamera update managed to sneak in.
