- Simplified Database structure to include only what is going to be used for the wallet.
- Properly distroy NetworkService connection when ConnectedActivty is distroyed to avoid crashes. - Created UserAccountRepository and AuthorityRepository to handle their corresponding database operations in an asynchronous way, because Room enforces database operations to be done in a thread other than the UI thread. - In ImportBrainkeyActivity when a proper brainkey is given save the imported account into the database, put a flag that tells the app there is a current account imported and send the user to MainActivity.master
