Drop-down for changing wallets

[jonbern]

It would be very practical to have a drop down (or similar) at the top of the screen, which would make it possible to change the selected wallet in wallet specific views.

For instance if you want to withdraw funds from multiple accounts, you could change the wallet instantly and remain in the "withdraw view", instead of having to navigate to "My Wallets", selecting the other wallet, and then clicking the "nahmii withdraw" toolbar button again.
