- install.xml updated with versions of tarfiles which no longer contain debug lib files on linux and darwin.  Files mistakenly added previously from automatically generated linux build dir (viewer-linux-i686) removed.  Also some dll's mistakenly added to linux lib tarfiles removed.

- file lists in assemblies/3rd_party_libs (used for updating lib tarfiles) updated as per above
- new config files created for 'glib' library; glib files removed from gtk-atk-pango-glib filelist.  glib can be decoupled from mono, when appropriate.

- package.py help dialogue and error reporting updated for clarity.
- install.py will now output list of files installed for a package with command-line option
