ed25519 keygen using Electron

This is a my first Electron application based on some electron sample code i copied from few github repos, it is a keygen and used to generate ed25519 keypair. Also there is an Apps menu to load a window that can be used to create hashes. I used linux for development. It can create linux and windows apps using npm run package-linux and npm run package-win respectively, you need wine installed for creating windows app though

Next steps

1. take seed from user input
2. use libindy to create keypair
3. save keypair with alias in sqlite
4. use sqlcipher
