rmw v0.8.1 released

• the curses menu library is now much more likely to be found on *BSD
  systems

• bugfix: when attempting to restore a file from a waste folder
  listed in the config file that has a trailing slash, rmw will no
  longer report that the file is not in a waste folder.

• curses is no longer a requirement (configure -Dwithout-curses=true)

• removed '-e' command line option ('--empty' option not affected)

To very signatures, use:

minisign -Vm <file> -P RWQ5AiSjYrIVoMPxKef7QdKLqQmiZvewAezjLCZHNUkE4/U0C48T3q4N
