modify parameters format to array for markdown-it plugin

[dwatow]

propose a new config way for the markdown-it plugin. you can install markdown-it-checkbox, markdown-it-abbr, ....and use config like this:

  "markdown": {
    "plugins": [
      "abbr",
      {
        "name": "container",
        "options": "success"
      },
      {
        "name": "container",
        "options": "info"
      },
      {
        "name": "container",
        "options": "warning"
      },
      {
        "name": "container",
        "options": "danger"
      },
      {
        "name": "emoji",
        "options": {
          "shortcuts": {}
        }
      },
      "deflist",
      "footnote",
      "imsize",
      "ins",
      "mark",
      "regexp",
      "sub",
      "sup",
      "checkbox"
    ]
  }

Looks like a great change. For me to merge and release this right now we'd need to make it backwards compatible, so support both formats.

Could you update dependencies of docpress in npm? I cannot use this modified version of docpress-core. thank you

Try reinstalling your version of docpress.
