Make STARTTLS LDAP option more precise on UI

[TuringTux]

Closes #129.

This also attempts to provide Spanish and French translations, however, they should ideally be reviewed by someone with better knowledge of those languages.

I have manually changed the string in the .php file and in one translation file (authorizer.pot), however, that translation file seems to be automatically generated, so I probably need to try doing this with POedit.

Edit: Done. Running Poedit changed quite a lot in the .pot file, but I only committed the changes relevant to this proposal.

This looks great, thanks so much! It will be included in the next release

Re: Poedit, I'm running a pretty old version myself and I think a lot of the formatting of the .pot output has changed between versions. Thanks for trimming that down to just the relevant changes, makes the code review easier!

Thank you for merging!

Yes, that is also what I suspected. I apologize for the bigger Spanish and French translation files, they are not trimmed to the max, because I had to update them from the .pot file and then somewhat lost track over the changes.

Aloha, version 3.6.3 has now been released. Thanks so much for your contribution!

That's very nice, thank you! I've just checked it and our production WordPress instance has already updated to the latest version, looks very nice indeed :)
