This makes `Document::GetShell()` return `PresShell*` instead of `nsIPresShell`.
Additonally, "shell" is unclear ("docshell" vs. "presshell"). Therefore, this
also renames `Document::GetShell()` to `Document::GetPresShell()`.
Similarly, some other method names of `Document` are also renamed from
`*Shell*` to `*PresShell*`.
