    Needs merge conflict solved here

    @luke-jr Mind to solve the merge conflict?

    Also, assigned 0.14 milestone, I think this is relatively trivial/uncontroversial refactoring.

    In theory, this should only be done when holding cs_wallet. I guess changing CWallet::strWalletFile to a const std::string is not possible with the current concept of setting the filename in a instance method. But maybe I’m wrong.

    Maybe declare CreateWalletFromFile() private to avoid layer confusion?

    It’s not really intended to be private…
