Revert "link mutt against ncurses (/usr/gnu/lib)"

This reverts commit 8fbd84832630cc976b0974551b5719725b9a5d35.

Apparently omnios ncurses doesn't work correctly? starting mutt in a
remote xterm with ssh in between just seems to suspend all output until
the ssh session is disconnected (since python-curses was linked against
ncurses this also applies to 'python -c "import curses;
curses.initscr(); curses.newwin(1,1,1,1);"')
change pkgrepo path
create user, group and homedir for ioquake3
add dovecot

does not include smf manifest yet; I'm only using preauthenticated
sessions locally (/usr/libexec/dovecot/imap) with mutt to get better
caching than mutt provides for maildirs.

note: the patch might be a bit unorthodox... I tried some defines as per
getopt(3c) and standards(5) but those failed with something else, so
it's just a quick hack to get dovecot running at all.
