cleanup of bootstraps and the hostenv

[liucougar]

1. Move the document methods to where they belong, which would be

hostenv_browser.js. This would include dojo.doc, dojo.body, and dojo.withDoc.

2. Find a way of writing dojo.withGlobal and dojo.withDoc without

using dojo.lang.curryArguments.

The bootstraps and the hostenv files should not ever contain any dependencies on any of the internal libraries within Dojo; and the bootstraps should contain no code that will not work in pure, raw JavaScript?. If I can't run the bootstraps in the context of, say, classic ASP with JScript, then the whole point of the bootstraps is lost.
