Add Ed back as a maintainer

I seem to be doing more and more architectural work these days on
bmcweb, so I might as well make it slightly more official by editing
this powerful text file.  I really would've prefered pulling a sword
from a stone, or been given a 2 factor encryption key by the lady of the
lake, but as monty python says "strange women lying in ponds
distributing swords is no basis for a system of government. Supreme
executive power derives from a mandate from the masses, not from some
farcical aquatic ceremony."

As such, I submit this to the masses for approval.
