* First rough setup translations/localization
* Also do sheet.php
I'm bad because I put a 'z' in my name...
Set name may be undefined
* Default language is first language found
* Unknown languages will be ignore and set to default language
* Added en-English.xml default language file
* Updated example translation nl_NL where it was still english
* Made _template/index.php translated
* Make sure English is the default, and first language
Remove debug code
Use dropdown for language selection; dont show if only one langauge
* Added some missing if-nested translations
* Removed some unused erronous 'name="Nederlands"' from files
Removed _template/index.php translations
* Add translate for mail (ajax messages & redirect)
* Minor tl() that should have been tlHtml()
