configurable language for fulltext-search

closes #2043

I love that you're tackling this ❤️

I am not sure what the default should be. I guess you used English as it is the current behaviour, but would it be possible to set it to "generic" or something like that, that is not language specific?

These KBIN_* options are still in use. Keep it in the example. right? Eventually we might need to rename all the configs with MBIN_ so its all consistent. but that is unrelated to this PR.

They are in the file, I just deleted duplicated keys (see lines 52+).

While I'm not fully against it, I prefer to have English as the default for the following reasons:

• most instances are English centered
• if set to English most instances would have to manually migrate to English search after the update to keep their current search behavior. Two such migrations can waste a lot of CPU time when the DB recreates the indexes.
• as the configuration is part of the setup docs for the admins, new instance admins won't miss the option for optimizing their search
