If you want to deploy the webtuna.js for SharePoint across the whole SharePoint Farm rather than modifying master pages for each Site Collection on each web frontend server then you can use the SharePoint Solution Packages below.
There are two steps to getting these setup, adding the package to a SharePoint farm (only needs to be done once) and then deploying it. The link below would give you the instructions to do this.
