Many missing characters (important ones)

[dumblob]

Hi, just installed this through F-Droid and was delighted by the simplicity and overall functionality.

I'm missing some crucial characters though (e.g. , ; etc.).

I've noticed the fork https://github.com/pobrelkey/techkeyboard does implement these.

I also noticed there are some new commits in this repo but no corresponding release in F-Droid repos (in fact the release in F-Droid is 9 years old!).

Would you @pi3ch consider merging the few changes from the @pobrelkey's fork and then releasing new APK to F-Droid?

Thanks a lot for this great & simple keyboard!
