retext: update to 7.1.0

## ReText 7.1.0 (2020-04-04)

* General improvements:
    - New files are now opened in new tabs by default, not new windows
      (contributed by Daniele Scasciafratte in #476). This can be disabled
      using `openFilesInExistingWindow` configuration option.
    - Preferences dialog improvements: it now uses tabs; added a link to
      configuration file (contributed by Xavier Gouchet in #327); clicking on
      checkbox label now changes checkbox state.
    - Return key now automatically continues quote blocks and ordered lists
      (contributed by Xavier Gouchet in #298 and #326).
    - It is now possible to close the current tab with Ctrl+W (contributed by
      Xavier Gouchet in #283).
    - Ctrl+wheel on editor now increases/decreases font size (contributed by
      Xavier Gouchet in #328). Ctrl+wheel in preview zooms in/out (#400).
    - Alt+Up/Down arrow now moves the current line up/down (contributed by
      Xavier Gouchet in #337).

      Xavier Gouchet in #382).
    - Table mode improvements (contributed by Maurice van der Pot).
    - “Paste Image” moved to a separate action, with Ctrl+Shift+V shortcut.

      (contributed by red-kite in #436 and Xavier Gouchet in #459).
    - Added a menu action to insert images from filesystem (contributed by
      Daniel Venturini in #500).

    - `relativeLineNumbers` — count line numbers as relative to the current
      line (contributed by Xavier Gouchet in #270).

      (contributed by red-kite in #407).
    - `windowTitleFullPath` — show full path in window title (contributed by
      red-kite in #429).
    - `defaultPreviewState` — mode for new tabs: `editor`, `normal-preview` or
