Add support for swedish words and keyboard

[strataro]

Hi there :) I made an attempt at adding swedish words and keyboard to the game, what do you think?

Thank you. I will test this.

Update:
There are two problems with this: Your code for hiding the accented keys doesn't work because keyboard.get("Å") returns null, the extra keys don't work, probably for the same reason, and the keyboard with the extra characters is too wide and may cause issues to be raised. This is on a Moto G running 7.1.2. Interestingly, it works on a Pixel 3a running android 15, including the extra keys. I test my apps on an old phone because some people who use FOSS apps tend to run unofficial ROMS on older devices.

It would appear that there is a problem with HashMap.get() with accented character strings on older versions of android. It may be something to do with the two objects not being the same object.

To make this work I have removed the extra keyboard keys and added the extra accents to the accents that can be added for dictionary lookup. That makes it work the same as all the other accented languages except Greek.

I have also used your dictionary for my Gridle app.
