Add valid permissions on .ssh folder and key files in *nix systems

To enable Linux/BSD systems to correctly work with you ssh keys - you need to set valid permissions for that files.

Typically you want the permissions to be:

• .ssh - directory to have 0700
• *.pub - public keys to have 0644
• id_rsa - private keys to have 0600

Shortcut script to make that works

This few commands works for me:

chmod 0700 ~/.ssh 
chmod 0644 ~/.ssh/*.pub
chmod 0600 ~/.ssh/id_rsa ~/.ssh/github_rsa
