- gui NewWindow takes SimpleClientIdentity as argument
- gui NewWindow takes ethutil.ConfigManager as argument to manage flag persistence
- gui now saves loglevel and custom client id via config.Save
- rename custom client id methods consistently also in wallet.qml
- clientIdentifier now set in main wrappers
- version handled within wrapper
- modify InitConfig now returning *ethutil.ConfigManager (passed to gui)

Feature/keys

- remove lib   *EthLib, expose gui itself to initial import window
- remove addr []byte instead use dynamic adress()
- use ethereum.KeyManager to retrieve address and privateKey
- add Session string (keyRing identifier)
- add and reimplement ImportAndSetPrivKey and CreateAndSetPrivKey

main loop uses new flags and common methods in util: db, keymanager set up; passes KeyRing/Session string to gui

- keyring: keyring/session identifier used by key manager
- keystore: choice of db/file key storage
- import message updated
- export: name of directory to export keys to (was bool)
