Wrong translation of formula function names and identifiers

Hi all,

Please have a look at this issue and the two attachments. The
list is sorted by language codes between translations/source/ and
/formula/messages.po
https://bugs.documentfoundation.org/show_bug.cgi?id=128200

Let me know when it's corrected in your language, then I'll ping
personally those who didn't fix the errors.
Thanks in advance!
Cheers
Sophie
