Use files in the source tree instead of cut/paste

Many of the large files are included in the tree and the script now
leverages a checked out swift tree to provide those files so that
users don't have to cut/paste text from the document. The contents of
those files are still included in the document for reference.

Updated to add sudo in appropriate places so that the entire script
can be run as the user instead of as root.

We also simplify the steps needed to get resetswift script working
(don't need to edit the user name).
