Travis CI: site documentation update at 2014-03-25 20:31:34 UTC.

Commit: https://github.com/urho3d/Urho3D/commit/de8396f0c4f1b3f8e177af12d9a40008029f0b5c

Message: Ensure StaticSprite2D calculates its local boundingbox correctly, then transforms it to world space. Remove DrawableProxy2D searching for a camera node, as that is unreliable. Instead a large bounding box (similar to SkyBox) is set for it.
