Adds several useful links to the Multisite "Network Admin" admin bar.
As a Multisite administrator & developer, what's the one task you most often need to accomplish from within the Network Admin section?...Manage plugins! Am I right? This plugin adds the network 'Plugins' and 'Install Plugin' links to 'My Sites' > 'Network Admin' in the site admin bar. Future releases will provide options to select which admin bar links to show or not show.
