Inspect Tool Update:
* remove hardcoded constants ("unknown", 19, etc.)
* bugfix (possibly endless loop) and simplification in library_from_content()
* generate valid XHTML 1.0 Strict when in HTML output mode (with link to validator)
* help output more consistent with the GNU style; return 0 when help is deliberately invoked
* added error control for strftime()
* add trailing slash to library URLs
* use <assert.h>, as some libs still macro-guard <cassert>
