This is purely internal sanitizing/cleanup, no change in behavior is expected at all.
This change was also needed because we were getting short on ID flags, and
future enhancement of 'user_one' ID behavior requires two new ones.
id->flag remains for persistent data (fakeuser only, so far!), this also allows us
100% backward & forward compatibility.
New id->tag is used for most flags. Though written in .blend files, its content
is cleared at read time.
Note that .blend file version was bumped, so that we can clear runtimeflags from
old .blends, important in case we add new persistent flags in future.
Also, behavior of tags (either status ones, or whether they need to be cleared before/after use)
has been added as comments to their declaration.

- SceneExporter collects a list of child-objects for armature-object and passes it onto ArmatureExporter
- SceneExporter's writeNodes is then called from ArmatureExporter for matching child-objects for bone.
- ArmatureExporter removes written child-objects from list, objects not exported as being bone parented are exported as direct children of the armature-node.
- Should play nice with current Second Life-compatibility.
A nicer implementation would require some design changes, will have to wait.
