preserve CamelCase

[JesseAldridge]

I used storm to parse my ssh config file for this tool: https://github.com/JesseAldridge/ssh_fixer Unfortunately, it seems the CamelCase is lost and the output looks a bit ugly.

Before:

Host repo_quality
    HostName 54.172.109.248
    User ubuntu
    IdentityFile ~/.ssh/id_rsa2
    Cipher blowfish

After:

Host repo_quality
    identityfile ~/.ssh/id_rsa2
    hostname 54.172.109.248
    user ubuntu
    cipher blowfish

This PR preserves the original casing.

Can you squash two commits into one commit? Looks legit.

Thanks for the contribution.

Done.
