Fixing typo Ammend -> Amend in chkAmmend.Text

Fixing typo Ammend -> Amend in chkAmmend.Text in English and updates all other translation files

chkAmmend and Settings.DontConfirmAmmend should also be fixed but then old saved settings in DontConfirmAmmend might get lost and currently I cannot open and fix them in the Designer myself

Suggestion: 
chkAmmend -> chkAmend 
DontConfirmAmmend -> DontConfirmAmend
