Refactoring to be more wrappable
Fix search/replace snafu
Fix search/replace snafu
Newline
Fixing 2 things:

1. When I refactored for wrappability, I accidentally used pxe rather than clonezilla for the appendline attribute. This is fixed.
2. Updating Clonezilla version to latest stable (as of 3/10/2014)
Fixing my own misunderstanding as well as tftp directory
Minor layout fixes.

Some rubocop stuff and some foodcritic stuff. Otherwise good work!
