added warnings (Options -> Show info window) if components are missing a name=... attribute / if symbols are missing a type=... attribute; eliminated usage of tcl "file normalize..." statements to avoid symlink dereferencing (if using symlinked libraries), aligned version/file_version tags in support awk scripts
