This patch changes all non-code, non-command instances of "DispVM" to
"DisposableVM". It also fixes a variety of orthographic errors
pertaining to this term, e.g., by correcting "Disposable VM" to
"DisposableVM".
- Correct "Use HVM" to "Use PVH and HVM"
- Link to QSB #37, which explains the use of PVH in addition to HVM
- Link directly to the full text of QSB #37. (Normally, linking to a
Qubes News post would be preferable. However, since QSB #37 has
undergone multiple updates, there is no single Qubes News post that
contains the full text of QSB #37. In these circumstnces, readers are
less likely to be misled by being taken directly to the full text.)
