hgext: more patchbomb documentation

+ Add a description of how to enable this extension

+ Note which command it provides (it's not very easy to guess
  that "hgext.patchbomb" enables the "email" command, unless one
  can read Python sources)

+ Expand the descriptions of the -n and -m options of "hg email".

+ Mention that formail is (commonly) part of the procmail package.
