Translation fix now only allows a single line in translation

This catches whenever the Japanese line fails to be detected as untranslated
Translationfix no longer deletes some comments (no loss in comments in git)
Translationfix will now start with the last file to give an error

Once this file can pass without error, the script discards the statistics and starts over normally.
If there are multiple errors, they often appear in the same file, which mean finding the next one will be faster this way.
Changed all translated text into using just a single line

This also fixes all cases where the script failed to detect untranslated lines due to minor modifications.
