Add lang word to existing language file

[CheetahShrk]

Don't know if its been suggested or not before, but one of the things I find ipb missing is the ability to add another language word to an existing language file, you can edit the language words but you can't add a new one. And I rather add a new language via acp then opening up ftp, downloading the lang file then adding the new word and reuploading.And also it appears in ipb 2.1 the lang files are considered as cache and that may be a problem if it works like the skin cache and you have to add a new language word.

* Be able to add new lang file/section
* Be able to add new setting
* Batch add ability

I could go for those ideas. I had been thinking about this too, but never got around to mentioning it. Thank you for doing it. :thumbsup:
