manpage update

Add -w|--windowtype.

Also --scores and --directory as recognized variations of -s and -d.

Add -@.  The existing description of '-p @' seems to be inaccurate,
and random role but still having to supply race+gender+alignment
isn't very useful anyway.  The bit about maybe needing to quote @ with
backslash might still be useful if moved to -@ though.

Add -A|-Arc -B|-Bar ... -W|Wiz since they hadn't been listed.  I put
them on their own line instead of cluttering up the main program
invocation even further.

Move '-u character-name' before '-D' since that order matters on some
platforms.

Move --showpaths and --version to a separate command invocation since
combining them with any other stuff ends up ignoring that other stuff.
I didn't add --dumpenums.

The description of config file name and location under '-dec and -ibm'
is out of date, particularly for Windows.
