Travis CI: site documentation update at 2013-12-30 12:50:06 UTC.

Commit: https://github.com/urho3d/Urho3D/commit/358d9c2849a28f0ecaceb61f983710b29894c937

Message: Added default tooltip delay to UI, which will be used if the tooltip's own delay is zero. Use seconds for tooltip delay to match eg. the doubleclick interval. Removed layout from the editor's tooltip root element to prevent it resizing in unwanted fashion.
