lib-fts: Added fts_language_register() to register more languages in plugins.

lib-fts: Add Norwegian. Norwegian has two main dialects, Bokmal(nb) and Nynorsk(nn). They are detected separately by libexttextcat, but the stemmer only knows Norwegian. Thus they are treated as a single language, Norwegian (no). This might also make more sense in everyday use of mixed writing style Norwegian. Caveat: The default normalizer filter does not modify U+00F8 (Latin Small Letter O with Stroke). In some configurations it might be desirable to rewrite it to e.g. o. Same goes for the upper case version. This can be done by passing a modified "id" setting to the normalizer filter.

lib-fts: Add comment to language names. Languages are defined by their ISO 639-1 code, which is a two letters. It is possible, that some languages with only a three letter code, ie. a ISO 639-2 code, could be added in the future.

lib-fts: Add Swedish (sv) to supported languages.

lib-fts: Added more supported languages. This includes now all the ones that are currently supported by both snowball and exttextcat.

lib-fts: fts_language_list_init() API changed to return errors.

lib-fts requires libexttextcat actually - don't even try to use textcat for it. I'm also not sure yet if some libexttextcats are too old for it.

lib-fts: Fixed default textcat datadir paths.

Initial import for lib-fts. Parts of what this code does was already implemented internally by fts-lucene. lib-fts is intended to be usable for all the FTS backends. The APIs are still going to change a bit, but hopefully not after v2.2.17 release. Mostly written by Teemu Huovila.
