####
#### Checks, if there are similar keys in the two inputfiles.
#### For example, check the current lang.pm (first input) and newphrases.
#### So if there are similar keys you don't have to translate
#### them again but use the old value and just modify it.
#### IMPORTANT: Both inputfiles have to contain a hash %Lexicon (like lang.pm) !!!
