This is based on bugreport #458 reported by viwrap who also made a nice test-case model.
Note: While solution seems to work and would even be faster, I'm not 100% sure yet if there are no downsides.
The other solution seems to regard last column in matrices - thought I don't think we ever set or use that.
And I also haven't found out yet _why_ the original solution goes wrong.
But animation system uses right-hand quaternions unlike rest of Irrlicht which is obviously a bit dangerous, will have to check the conversions some day.

It still won't work yet for scaled boundingboxes (or parents being scaled).
But at least it's now large enough for typical unscaled boundingboxes.
Before it was always too small - even for the simplest quadratic billboard case seen without rotation.
Now it's always a bit too large, but that's way less of a problem (collisions still work and culling simply happens a bit less often, but not too often which is way worse)

First problem was that IGUIElement::getNextElement wasn't passing includeInvisible and includeDisabled flags recursively, so anything deeper than one level could fail if an element was disabled/invisible in between while it was created.
Second problem was that setTabOrder(-1) did ignore disabled elements. So when any parent was disabled when elements were created they never got a tab order.

Lots of places where coders did not realize our Printer::log with hint adds a ": " string between message and hint
Which caused uglier messages in a few places (added documentation for that, maybe helps?)
Some added info in a few places
Some whitespace unification
Some spelling unification

color intitialization has some cost, but we initialized all other values already (vectors are always set to 0).
Don't think it's a good idea to have one value around which is random.
S3DVertex2TCoords(S3DVertex& o) to S3DVertex2TCoords(const S3DVertex& o) simply because it makes more sense
S3DVertexTangents(const S3DVertex& o) added because I'll need it later (and no idea why only S3DVertex2TCoords got one of those before).

Other functions like getMaterialRendererName got switched to u32 in the past. I can see no reason why this one was left out, so changing it to be same as the rest.
