v0.15.1 release.

`bitcoin-qt` opens the wrong conf file when a conf file is specified with `-conf={file}`

Key:

    >bitcoin-qt -conf=altconf.conf

Go to: Settings --> Options --> Open Configuration File --> OK

Editor opens with `default.conf` instead. Should open specified conf, also using `-datadir={folder path}` parameter which I have not checked.
