Add back fixes that were in Singularity (in indra/media_plugins) but not in imprudence. Also: Add "shutdown" plugin message and terminate file picker plugins cleanly. The DSO (libbasic_plugin_filepicker.so) now tells the child process / plugin loader (SLPlugin) to terminate (using the 'shutdown' message), and AIFilePicker::finish_impl destroys the plugin object on the viewer side when it's ... finished thus. Also added a large comment that gives an overview of all classes involved on the viewer side. Additional fixes for filepicker. Plugin refactor bug fix: mDeleteMe was uninitialized in AIPluginFilePicker.
