Walletwasabi: Change password masking to Japanese/Chinese characters

Just for the fun of it.

In this issue #439, @nopara73 reported a critical bug in wasabi: not enough fun and giggles.
This got fixed in #1037.
Though unfortunately, some reported the bug fix, to be the bug itself #1118!
This lead to a lot of confusion, and a critical bug got introduced again in #2187.

I agree with nopara, that this is the most important feature, and that removing it was a big mistake!

So, [nopara is gonna love this] I propose to re-consider the decision :rocket: and bring the fun back to wasabi!

On the technical side, I disagree. The Chinese PW box was a huge hack and we had recurrent issues reported by users when they had the so-called WTF moment with Wasabi. Since we changed to this boring one not a single issue or tweet was made regarding this.
