[SteamAppNewsBridge] Add tags filter

[God-damnit-all]

Adds a tag filter that retrieves newsitems entries containing the listed tag(s).

The most common use-case is for retrieving entries with the patchnotes tag.

This uses the currently undocumented tags parameter, which can be discovered through a GetSupportedAPIList query. It takes a comma-separated list as an argument, and it's allowed to be an empty string.

GetNewsForApp v2 entry via /ISteamWebAPIUtil/GetSupportedAPIList/v1/

{
  "name": "GetNewsForApp",
  "version": 2,
  "httpmethod": "GET",
  "parameters": [
    {
      "name": "appid",
      "type": "uint32",
      "optional": false,
      "description": "AppID to retrieve news for"
    },
    {
      "name": "maxlength",
      "type": "uint32",
      "optional": true,
      "description": "Maximum length for the content to return, if this is 0 the full content is returned, if it's less then a blurb is generated to fit."
    },
    {
      "name": "enddate",
      "type": "uint32",
      "optional": true,
      "description": "Retrieve posts earlier than this date (unix epoch timestamp)"
    },
    {
      "name": "count",
      "type": "uint32",
      "optional": true,
      "description": "# of posts to retrieve (default 20)"
    },
    {
      "name": "feeds",
      "type": "string",
      "optional": true,
      "description": "Comma-separated list of feed names to return news for"
    },
    {
      "name": "tags",
      "type": "string",
      "optional": true,
      "description": "Comma-separated list of tags to filter by (e.g. 'patchnodes')"
    }
  ]
}

^{I think the example in tags's description is supposed to be 'patchnotes', not 'patchnodes'.}

Because I haven't been able to come across any news entries that have more than one tag, I refrained from making this bridge parameter the list type, as I felt that might suggest it utilizes an OR list rather than an AND list.

[dvikan]

some linter issues

[God-damnit-all]

@dvikan Apparently the nice spacing I put in to make the variable vales line up was a waste. I went ahead and removed it. Should be fine now.

[God-damnit-all]

Apparently it doesn't like the newline after the variable statement, sorry about that.
