minor bug fixes

Initial Release

  Jekyll Manager is an open source project, forked from the official
  plugin Jekyll Admin, and repackaged with some alterations and
  additions, a few of which, may eventually be included in the official
  version.

  Notable alterations:

    - Sidebar routes cannot be manually hidden. They're rendered based
      on whether Jekyll has read-in at least one file of the concerned
      type.
    - Routes to Collections other than Posts are hidden within a
      collapsed list-item by default.
    - Metadata fields for front matter are hidden with a collapsed
      section by default.
    - Input path fields show / require the full `relative_path` of the
      requested file.
    - Minor style changes.
    - Other miscellaneous changes.

  Additional Features:

    - A basic dashboard that provides insight on the current site and a
      means to add files to cetain empty content types (Pages, Posts,
      Data Files, Static Files).
    - Draft posts can be created and edited via the admin interface
      provided your config file has `show_drafts: true`.
    - Template files (files within `_layouts`, `_includes`, `_sass` and
      `assets` at the root of your site) can be edited via the
      interface.
    - Template files (and files within any directory) within a
      theme-gem can be viewed and copied over to the source directory
      for editing.
    - Ability to select layouts for a document based on available
      layouts in the Site.
    - Special metadata field for tags.
