ValExtLinks improvements:
- Now advises reader of external internal links.
- The exceptions file now allows finer-grained exemption of a URL by matching to the specific page that contains it instead of exempting all occurrences of that URL (but the '*' wildcard will match all containing pages). Currently you can only list a URL once, however.
- The exceptions file now allows external internal and potential intrawiki links to be exempted from the report.
- The path to Google Chrome (for taking screenshots) is now external to the script, supplied as an argument after "--take-screenshots".
- All of OniGalore's interwiki shortcuts are now recognized.
- Protection against failed retrieval of redirect URL.
- Better recognition of unimportant redirects (http->https, added ending slash).
