Devlog 2 Polishing the ui and adding more underlying stuff that we will need in the future so

So in this we added to two big changes

• First is the completely reworked set up it to make it a little bit more pretty and polished looking
• And the other one is its a more of an underlying change but a well needed one because in the previous demos it stored the key pairs in plain text and stuff so that is obviously super dangerous in a secure messaging context so it will now let you encrypt it via a pin you set in the account creation like in the real signal
