Added setDrawBorder to IGUIEditBox and IGUIStaticText. 
Added setTextAlignment to GUIEditBox and IGUIStaticText, for text justification and vertical alignment.
IGUIEditbox now supports multiple lines using setWordWrap and setMultiLine.
IGUIElement now calls getter and setter functions when serializing, in case of getter/setter overrides.

changed the docs of quaternion to state the euler angles used are in radians, this seems to have confused someone on the forums, so it did me before. check I'm right about this.

Box = Mesh->getBoundingBox(); //can we remove this, the box is set on 'setMesh', and without it the user can set their own boundingbox (if the normal one is too small) without it being overwritten

couldn't work out why oct-trees were culled against the bounding box of the frustum rather than the frustum itself. works better than the bounding box method in my test meshes (box method culls too much) so I changed it back to use frustum method.

changed CAnimatedMeshSceneNode to use the bounding box of its IAnimatedMesh instead of calling getMesh() and re-skinning. Tested with a few different mesh formats and couldn't see any obvious problems. IAnimatedMesh implementations are now responsible for keeping a maximum bounding box.
