Remove # $FreeBSD$ from Makefiles.

Rename the magic DISTVERSION into SPELLVERSION for the aspell ports.

Sponsored by:	Absolight

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

Bump portrevision due to upgrade of devel/gettext.

The affected ports are the ones with gettext as a run-dependency
according to ports/INDEX-7 (5007 of them) and the ones with USE_GETTEXT
in Makefile (29 of them).

All dictionaries can be installed separately:

  - by default, textproc/aspell installs the English dictionaries (no
    change);
  - thereafter you can install any foreign dictionary;
  - when you install a foreign dictionary, i.e. french/aspell or
    textproc/da-aspell, it installs only the dictionaries, and depends
    upon textproc/aspell for the programs;
  - if you don't need the English dictionaries, you can define
    WITHOUT_DICTEN or install textproc/aspell-without-dicten;
  - add a new port for textproc/en-aspell: if aspell had been installed
    without the English dictionaries, they can be added thereafter;
  - add a missing port for german/alt-aspell;
  - foreign dictionaries are almost independent from textproc/aspell,
    and their maintainership is available.
