Maya camera no longer get's stuck in "rotating" state when a mouse-up event is lost (thx @ JLouisB for reporting).

Focus behavior of IGUIEnvironment now controllable (right-click focus, mouse-over focus). Disabled elements no longer get the focus unless users enforce it.

- Irrlicht elements can't just set ID's otherwise user-elements stop working.
  So anyone who had gui-elements not working with ID 0 or 1 - you probably had a guitree somewhere.
  Those ID's were not even used...
- Make the horizontal scrollbar (mostly) work. Selection still messed up, but was that way before and least h-scrolling works now somewhat (did nothing before).
There are more bugs in this gui-element - like that it doesn't draw the last line regularly. 
But I have no more time, nor motiviation for this now (not the first time finding pretty obvious bugs in the treeview. 
I wish that d*mn thing would never had been checked in. Or the original author would at least have tested it or cared about maintaince!).

Remove lot's of setFocus and removeFocus calls. Also several places where elements check if they have the focus inside events.
Slightly risky change - but it's hard to improve all this without cleaning it up first. And most elements should _not_ be responsible for their 
own focus but the guienvironment should do that (and does do it).

Buttons can now now have 7 more image-states, 1 more sprite-state and the sprites are now scaleable.

Reverting last changes - there is more stuff broken with generating documentation, so I suspect the real troubles is the layout file.

Our current member function documentation look often rather strange. The reason is that the first 
line in multi-line comment is handled special (it get's a box around it). So in the cases where we use
this for \param or have sentences starting in that line and continuing in the next it always looks broken.
Please click for example through IGUIElement documenation which is not yet fixed to see this.
Also links to enums don't seem to need @ref but just ::my_enum_name.

Japanese not yet, but we're even a little closer to that now.
Dead-key handling is not working. I just can't figure it out (X11 documentation and examples make me swear badly).
Users which have language input with dead-keys (like ^) will now have those characters always ignored.
Before it had just printed the characters but set a complete wrong key-code. So dead keys partly better, partly worse.
But this solution is going in the right direction. Either we figure out later why X11 doesn't handle dead-keys or we handle them ourselves.

Fix: Buttons can now change the image several times and the pressed image will always be updated. Fixing Bug #197 by some anonymous coder.
Note that the way this works might change again soon (I just wanted to fix old version before rewriting it).

Ensure vector3df and all classes containing a vector3df are passed by reference instead of per value. Thanks @Danyal Zia for the patch (#280).
This is breaking the IAttributes interface - so anyone who derived from that will have to update his implementation. More changes in that interface probably coming later today.
The idea behind the patch is preparing the engine for SSE support.
