Improved i18n key input for X11. Which means languages like cyrillic work now.
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.

Cleanup - membervariables start with uppercase letters.

Fixing doxygen layout for ISceneNode. Same should probably be done throughout.
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.

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