Log Message:
Moving ispell-* packages as discussed on tech-pkg@. Reasons being:

1) Shorter package name;
2) Be consistent with kde3-l18n-*, kde4-l10n-*, hunspell-*, aspell-*,
lang-* PKG_OPTIONS;
3) Simplify modifications to PKGNAME in some Makefiles;
4) Accordance with international language naming standards;

and rename the ispell-base package to ispell, to be consistent with aspell
and hunspell. Bump PKGREVISION where necessary.
