PHPLOY_PASS environment variable ignored when using a private key

[VladimirCatrici]

I'm using a private key with a passphrase set up as environment variable PHPLOY_PRIVKEY and it only works when password explicitly specified in phploy.ini. In doesn't work when password specified via PHPLOY_PASS environment variable. When both "pass" in phploy.ini and PHPLOY_PASS are missing, it never asks for a passphrase on deploying, but I think that's another issue that has already been reported (#343).

I'm using PHPloy v4.9.1 on Windows 10.
