* Bump aspell_en to 2016.01.19-0 and switch it to "any" arch.
* Do not use 2016.01.19_0 but 2016.01.19~0 (i.e. with a tilde instead
of the underscore) in the name of the recipe in order to be able to
define SOURCE_{URI,DIR} using "${portVersion/\~/-}", thus avoiding
hard-coded version-related strings in the recipe.
* Remove from aspell_en's DESCRIPTION what's already in aspell's.
* Add: de (German), es (Spanish), it (Italian), pl (Polish), pt_BR
(Brazilian Portuguese), pt_PT (Portuguese), ru (Russian).
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used
for building a package.
