New version that mostly adds lots of requested features:

• Add options to quote the path for (a) plugin(s)
• UNC Path for default shares
• Network deployment with install options
• Allow user to choose what the default plugin is

This version also features a more elaborate Settings UI that has several tabs. I tried to add some notes to better explain the use and purpose of the various options.

The Path Copy Copy documentation is also available, both to explain how to develop custom plugins and to explain how to pre-configure options if you're a network admin.
