mandrake 1.1.1 - Handle exceptions thrown by styler

Mandrake 1.1.1

Fixes

Frontend Dependency Management

Fix dependency problems when using attach_dependencies(standalone = TRUE):

• bootstrap
  • Fully embed entire bootstrap package, including all assets, not just css
  • Attach src from top level of bootstrap, so all assets are bundled.
• jquery:
  • Fix missing package argument in jquery's htmlDependency()
    definition
• attach jquery & bootstrap dependencies before other frontend dependencies,
  as other dependencies require jquery (especially) to be loaded already.
  • I named a fixup commit "idk", sorry @me [aebf937] [a2eb660]
• mustache templates:
  • Fix outdated refEREnce to template file test.html.mustache, which was deleted.
  • Now include display.html.mustache

Frontend

• make embedHandler() backwards compatible with graphs generated by
  mandrake<1.1.0
  • In mandrake<1.1.0, R generated html directly and this was passed to
    visNetwork to be rendered directly
  • In mandrake>=1.1.0, R encodes the data into json & passes this object
    to visNetwork, which can be decoded & flexibly rendered by the frontend.
  • Now, embedHandler() tries to parse the input as json, then rendering it
    into a template, but if JSON.parse raises a syntax error, the input will be
    given directly to the DOM
• (Everything to be given to the DOM is still cleaned by DOMPurify)

Backend

• When styling code from plan commands, now wrap styler::style_text() in try block
• That way, if code that can't be parsed by styler (eg, contains a pretty printed quosure),
  it won't crash the workflow

Misc

• Remove "Remotes" section from DESCRIPTION, change a few dependency packages from github/development head to
  CRAN
