Hello,

I have found 2 really annoying bugs in this plugin :
1. If you translate custom fields for which DB name is like idCommercial__idContact ... then the translation file (lang.js) knows the translation key as colPlgIdCommercialIdContact and the label isn't properly displayed in the gui. If the key is manually modified in lang.js  to colPlgIdCommercial__idContact, then everything backs to normal. Expected behavior would be to avoid deletion of "__" characters when saving translations.

2. Struggling with this previous one, with the gui, you can insert a second identical key in the lang.js ... and then the translation plugin is out of order until you delete one of the two identical keys. Expected behavior would be, when saving, check for ducplicate entries and avoid to write it.
