Restructure Canvas/PropertyBasedElement
Nodes inside the osg scenegraph now hold a strong reference to
the according canvas element. Canvas elements in turn now only
hold a weak reference to the according node. This simplifies
for example the canvas::Group as it does not need to keep a
list of children on its own anymore. This is now stored inside
the scenegraph (as it was already before).
The restructuring will also allow to use a canvas::Group for
the canvas gui inside FlightGear and share for example the
handling of stacking based on z-index.

Canvas: clear event listeners on destroy
Removing all event listeneres on destroying a canvas
prevents circular references due to Nasal event listeners
keeping a reference to the canvas in their closure.
Also fix event handling with direct children of the root
group and add some more helpers to the Canvas.

Extend locked-track animation to support a slave element.
This allows tracking elements while at the same time changing the
rotation of both animated elements to fill the available distance
to the target element. This allows for example animating gear
scissors or other connected objects like gear doors and their
actuators/arms (possibly connected to the gear strut).

Canvas: rework style setter system.
Style setters are now only setup once for each element type and
not for each element instance as before. A static map holds the
setters for each element type. Also an animation type is stored
which will later allow to animate properties of Canvas elements
without specifying and animation type.

Restructure to avoid ordering issues.
Create a pick group for each object, instead of a single one. This
can be optimised in the future but this structure is backwards-
compatible with existing usage, which is more important.

Support for proxy pick objects.
Pick, knob and slider animations support additional object-names,
which are always invisible and untransformed (in the case of knobs/
sliders). These objects act to extend the hover/pick area, making small
switches and knobs more usable. (Especially for users with smaller
screens / windows).

Ensure every scenery model has own SGModelData.
This makes Nasal unload hooks of scenery objects working again.
Previously the same SGModelData instance was used for all objects
which never got destroyed and therefore was not able to call any
unload callback.

New interpolation/animation system.
Inspired by jQuery.animate() properties can be interpolated using
different easing functions and specifying an animation duration.
Additionally animations can be chained to get table-based
animations like with the current SGInterpolator, or also create
looped animations or other more complicated curves.
Currently this system is not used yet, but it is intended to
replace SGInterpolator and allow more advanced animations of
eg. also colors, for example, for the canvas.

Collect properties from expression/condition trees.
Initial ground-work to support efficient updating of condition/expression results; allow collecting all the dependent property values from the hierarchy, so they can be observed. Also add a very small test-case for this.

cppbind: refactor to_nasal for better name lookup.
Using template parameter dependent name lookup it is
now possible to create to_nasal_helper overloads
for custom types and having them used for automatic
type conversion with binding methods/member on
nasal::Ghost objects.
