Remove # $FreeBSD$ from Makefiles.

- Install font files to ${FONTSDIR} instead of ${DATADIR}.
- Stop to make symbolic links from the font files to
  ${PREFIX}/share/fonts/misc/, which is found in the default
  font path, because recent libXfont does not follow symbolic
  links.
- Add pkg-message.in to show additional font path settings.
- Bump PORTREVISION.
- Set submitter as maintainer.

Fix inconsistent installation directories of Japanese fonts and
reorganize the package names:

 (new)     -> font-ayu18
 (new)     -> font-ayu20
 k10       -> font-naga10 (also builds "marunaga" variant now)
 k12       -> font-kaname12
 (new)     -> font-elisa10 (resurrected)
 elisa8x8  -> font-elisa8
 kanji18   -> font-kanji18 (also builds 16-dot variant now)
 kanji26   -> font-kanji26 (also builds 24-dot variant now)
 kappa20   -> font-kappa20 (Ayu fonts is separated into font-ayu20)
 mikachan-ttfonts -> font-mikachan
 monafonts-ttf -> font-mona-ttf
 monafonts -> font-mona

All of bitmap fonts are now installed into misc/, and the TrueType fonts go
into TTF/.

No objection from:	maintainers
