translation: Move translation activity to subdirectory

And also move wordlist to own directory $storage/Voldemars/wordlists/
to prepare for multiple wordlists. Unfortunately changes are
obfuscated in the file move although smart diff (git diff--find-copies-harder)
should make it visible. Changes mostly in WordlistLoader

wordlist: Add wordlist.zip

This way we'll be able to embed more than 1 wordlist file.
