Maintenance of page - adding new languages

Reported on bugzilla 28736.

Some more small problems with the categorisation. Portal:Tw is not included in the category Languages without translators and this category is not listed at the bottom of the page. This language is supported although it has no translations nor any translators as yet. The portal Tokipona is also not included in the category Languages without translators but it is also not supported. I don't know enough about wiki syntax to know whether the reason for this is the way the template Portal is written, or whether it is another problem with category collation. I won't report this on bugzilla unless requested to do so by a staff member.

As of today the category Languages without translators contains 64 languages without translators which are supported by translatewiki.net, and it should contain one other language as explained above.
