add "translate" function in vmi.py

[mintancy]

An error occurred while running the psxview plugin:

# python vol.py -l vmi://winxpsp3x86 --profile=WinXPSP2x86 psxview
AttributeError: 'PyVmiAddressSpace' object has no attribute 'translate'

After checking the libvmi address plugin, there is no translate function in vmi.py file. So I tried to add these code at the bottom:

    Def translate(self, addr):
        Return self.vmi.translate_kv2p(addr)

And I also modified the code in [malware/psxview.py] (https://github.com/volatilityfoundation/volatility/pull/362/commits/ca42f0c465c9acd9cc0b70e468af23a869e547fa) then I got the results:

Is this a correct result, or is this "translate" function right?
