NSIS installer - Add multilanguage strings

Please check installer script.
Added multilanguage strings (original messagebox strings were hardcoded in English).
Note: in original nsi script was declared "UninstLogMissing" variable that should contain text string but was not defined.

We will also need these strings to be added to the pot file and then have a way how to get the translations from po files back to the installer.

I believe that for now you can use the strings in NSIS script.
In the futire if you will find how to use in po and get in NSIS you can switch to this method.

Actually, can you in that case add the missing UninstLogMissing? It can say something like "Unable to uninstall ${APPNAME}, the ${UninstLog} file is missing.

It seems that I already fixed the issues.
All "Messagebox" reference point to a string that is in lnSIS script.
No one UninstLogMissing reference in the script.

You are right, I misunderstood the code in the script. I thought it's a dialog that says it fails to uninstall FMW, because the file is missing. Looks good to me now.
