Support OnHttpRequest Lua callback

Browse source 
If your redbean `/.init.lua` file defines a global callable named
`OnHttpRequest` then redbean will delegate all serving control to
your function. You may then restore the default serving paths, by
calling the new `Route()`, `RouteHost()`, and `RoutePath()` APIs.

Closes #150
