Tweaks and modifications

[koenpunt]

A summary of the changes:

• Added global option :as_user for all installers (Sprinkle::Installers::Installer) to run commands as specific user (su -c '....' -s /bin/sh #{@options[:as_user]})
• Added :sudo as global option for all Sprinkle::Installers::Installer classes
• Updated readability of the push_text and replace_text installers

[koenpunt]

To run commands under a specific user. For example the installation of rbenv under my deploy user. And not having to change file ownership after creating them

[joshgoebel]

Why wouldn't your default user be "deploy" in that case with sudo when needed?

[koenpunt]

Because the deploy user has restricted permissions on the system (specific commands in sudoers file)

[joshgoebel]

Which user is sprinkle connecting as then, root?

[koenpunt]

Nope, another user with full sudo rights.

[joshgoebel]

Isn't as_user something that really more applies to runner than to the installer base class? I guess I'm continuing this discussion to see if there is still a place for us to use as_user, since it's interesting.
