Bot Log Parser enhancements

[stuppie]

To the Bot Status page:

• add columns for updated/nochanges/errors/warnings
• split "Log Path" column into "Log Report", which contains the html report logs

To the reports:

• Would be nice to make the external IDs links. e.g. Grab the formatter url from the "Prop" column and use it to convert the "External ID" column into a link. This would make it easier to work on problem items
• Make it more clear that on items processed successfully, "SKIP" means no action was taken because the item is already up to date.

Would be nice to format the WDapi error responses too. e.g: making the QIDs clickable

     "error": {"code": "modification-failed",
               "info": "Item [[Q27826279|Q27826279]] already has label \"The importance of an innervated and intact antrum and pylorus in preventing postoperative duodenogastric reflux and gastritis.\" associated with language code en, using the same description text.",
               "*": "See https://www.wikidata.org/w/api.php for API usage",
               "messages": [{"name": "wikibase-validator-label-with-description-conflict",

                                 "en",
                                 "[[Q27826279|Q27826279]]"]}
                            ]
               }
     }
