This fixes the animation bindings to use the defined property tree root - to support multiplayer (or other) model that can bind to the correct part of the property tree. Requires a corresponding fix in fg to allow the command methods to take an optional root parameter. What this means is that when inside someone else's multiplayer model (e.g. backseat, or co-pilot), the multipalyer (AI) model will correctly modify properties inside the correct part of the property tree inside (/ai), rather than modifying the properties inside the same part of the tree as the non-ai model. This means that a properly setup model will operate within it's own space in the property tree; and permit more generic multiplayer code to be written. This is probably responsible for some of the pollution of the /sim property tree with MP aircraft properties.
