Adding a Save button in Atom Status Bar

README.txt

Install the 'reload-button' package.
Open it and click View Code.
Open the reload-button-view.js file and update the code.
Save file and relaunch Atom.

Note: There is no save icon in Octicons, so I settled for another one.

Diff is included for the curious.
