Deprecate .bind("ready") event

Description
The "ready" **event** is error prone because users may attach an event handler after it has fired. It is much more natural for ready semantics to follow the Promise model; if handlers are added after the document is ready then they will fire. We're adding a ready Promise in 1.8 (see #11470) and of course the standard $(fn) or $().ready(fn) continue to work without change.
Let's deprecate the ready **event** as of 1.8; there is no hurry to remove it, but let's help users avoid dumb errors caused by dumb APIs.

Documentation updated.
Just to be absolutely clear what is being deprecated here, it is these forms:
$(document).bind("ready", fn); $(document).on("ready", fn);Where "ready" is a custom event name that is only fired **once** by jQuery when the document becomes ready.
