Binpatches aren't used much at the moment, so this has two purposes:
collate information so it's easier to write them again, and remove it
from other sections where it's useless.
Note that if the standalone binpatch.exe is removed, the 'patching on
disk' section can be cleanly removed from 'Using a patch' by deleting
lines 44-47 & 61-90.
Checked with a throwaway script, and added the missing entries. NEWS
now has a comment on how to use the file, which is only visible in the
raw text version. Added the documentation changes to NEWS.
