Adding an optional light manager that allows hardware lights to be turned on... 

Adding an optional light manager that allows hardware lights to be turned on and off before each scene node is rendered. This can be used to produce "zoned" lighting.

If a light manager is not registered, the existing behaviour (activate the closest lights to the camera) will be retained unchanged.  New example project added to demonstrate the usage, and regression tests and existing samples run.  No regression test for the light manager yet, since I am more interested in not regressing the default behaviour.

Changes in version 1.6
- Added an optional light manager to the scene manager to allow the user application to turn lights on and off during scene rendering. This can be used to produce "zoned" lighting. See example 20.ManagedLights.
- Added a method to flip the Y movement of the FPS camera.
- The Anisotropy filter can now be set to the AF value per texture layer. So no forced MAX_ANISOTROPY anymore. .irr files will probably fail, though.

/*
Normally, you are limited to 8 dynamic lights per scene: this is a hardware limit. If you
want to use more dynamic lights in your scene, then you can register an optional light
manager that allows you to to turn lights on and off at specific point during rendering.
You are still limited to 8 lights, but the limit is per scene node.
This is completely optional: if you do not register a light manager, then a default
distance-based scheme will be used to prioritise hardware lights based on their distance
from the active camera.
NO_MANAGEMENT disables the light manager and shows Irrlicht's default light behaviour.
The 8 lights nearest to the camera will be turned on, and other lights will be turned off.
In this example, this produces a funky looking but incoherent light display.
LIGHTS_NEAREST_NODE shows an implementation that turns on a limited number of lights
per mesh scene node. If finds the 3 lights that are nearest to the node being rendered,
and turns them on, turning all other lights off. This works, but as it operates on every
light for every node, it does not scale well with many lights. The flickering you can see
in this demo is due to the lights swapping their relative positions from the cubes
(a deliberate demonstration of the limitations of this technique).
LIGHTS_IN_ZONE shows a technique for turning on lights based on a 'zone'. Each empty scene
node is considered to be the parent of a zone. When nodes are rendered, they turn off all
lights, then find their parent 'zone' and turn on all lights that are inside that zone, i.e.
are descendents of it in the scene graph. This produces true 'local' lighting for each cube
in this example. You could use a similar technique to locally light all meshes in (e.g.)
a room, without the lights spilling out to other rooms.
This light manager is also an event receiver; this is purely for simplicity in this example,
it's neither necessary nor recommended for a real application.
