Travis CI: site documentation update at 2014-03-09 22:50:10 UTC.

Commit: https://github.com/urho3d/Urho3D/commit/65c3c5073877c5034fb293f75054e4155c050548

Message: Shuffling around of Spline to the Core library to make explicit that it depends on Variant (the dependency is no longer strict as Urho3D library is built as one piece, but is good to keep in mind to retain the Math library theoretically reusable outside Urho3D.)
Register DebugRenderer earlier in the AngelScript API registration for less special cases.
