Travis CI: site documentation update at 2014-08-28 11:16:05 UTC.

Commit: https://github.com/urho3d/Urho3D/commit/3f5280aa3a7d8757bf158d7552d749795c520c39

Message: Add one second delay to file change notifications by default. Possibly helps with #408. Removed FileWatcher from Lua bindings as it's not a class you can readily use from script and it is not exposed to AngelScript either.
