[PATCH 0/6] MR2069: jscript/mshtml: Misc fixes and preparations.

[Gabriel Ivăncescu (＠insn)]

Bunch of misc fixes and preparations for further improvements. The location changes are especially important later when we'll use outer windows everywhere we pass them to external callers (such as script engines, since inner windows are an implementation detail and all operations otherwise should go through the outer window "proxy").
