Two people have mentioned this already, and there may be more out there wondering why the icon is no longer appearing. Simple answer, every time I update the plugin I have to learn how to use SVN all over again, which inevitably causes problems. Thankfully the fix is simple enough.
If you are on version 1.8 of the plugin simply updating to 1.8.1 will fix the issue. However, if you are already on version 1.8.1 and the icon is still not appearing you will unfortunately have to delete and reinstall the plugin, but I can confirm it will fix the issue.
Most importantly I learned something and will not make this same mistake again.
