Update config parser to support warning messages from vagrant.
Also remove the "" from the IdentityFile - should help for #4.
Use start flag to parse only host related info from ssh-config. Remove regex and fetch all values. It is assumed that the values are all key-value based spaced with a space and no space in the value.
Simplify cleaning and small fix.
