The fixed crash loop release

Corrupted files could put a stop to startup.

• Core:
  • Add a link to the Discord server from the feedback dialog.
    I hope that people will use it instead of bug reports to ask questions,
    or that the one asking questions in GitHub issues will read my answers there.
  • PLM should now survive to a corrupted ~/.plm directory and restore the session.
• Universes:
  • Buggles: clarify the name of Directions in the documentation
• Peagogical content:
  • lessons/recursion/cons/Concat: Fix a copy/paste error in Python
  • lessons/recursion/cons/ButLast: Fix a copy/paste error in the test instances
  • lessons/recursion/cons/Occurence: was broken in Python
  • lessons/welcome/traversal/SnakeEntity: translations were breaking Python
• Translations:
  • Updated: Portugese, thanks Silvério Santos.

The Portuguese release

We now have complete translation of the PLM in Portuguese

• Core:
  • Introduce a new Portuguese translation, thanks ssantos.
  • Introduce a new Swedish translation, thanks Kristoffer Grundström.
• Pedagogical content:
  • recursion/lego/spiral:
    • clarify in text how the learner's code is called automatically

The Saved Session Release.

Fix a bug preventing the user code from being saved on disk.

• Core:
  • Also distribute a all-in-one archive for Mac OSX.
• Pedagogical content:
  • Introduce a new Ukrainian translation, thanks Yuri Chornoivan.
  • welcome/methods/returning:
    • clarify in text how the learner's code is called automatically
    • allow backward(n). Parameters are introduced later, but loops
      are not the focus anymore at this point of the lesson.
  • welcome/methods/slug/SlugTracking:
    • clarify in text how the learner's code is called automatically
    • Add wall on the first world also, to show what they are.

The Windows release.

• Core:
  • Make it work on windows, thanks to appveyor.
  • Make sure that the save directory is created before using it.
  • Add the student code to the GitHub automatic bug reports.
• UI:
  • Make it possible to open the mission text in an external windows.
• Buggles:
  • Display the buggles' errors in the verbose world diff.
  • Translate these messages even in the Python bindings.
• Pedagogical content:
  • Hide the functions in welcome/variables.java: That's too early.
  • In 'stairway to heaven', we are using a global variable to count the amount of steps done so far. Rename it inTeerNal_Steep_Count to ensure that it will never clash with any variable created by the learner.

The 2020 release.

• Update dependencies so that it works nowadays
  • Update scala to v2.11.12 (v2.11.4 did not play well with Java11)
  • Update jython to v2.7.2~rc1 (to avoid a scary warning at startup)
  • Add dependencies to the jar, so that it works on a naked machine.
• Worlds:

    forbidding forward() with a parameter (#512, #518).

    - #495: Fix pseudo-markdown in MethodReturning in French
  • #490, #493 : Make clear that writing growFlowers() is part
    of the FlowerPot assignment

  • #495: Strenghten the checks for errors in [!python] and such
  • Kill the broken feature of Courses. Should be redone another way.

The Pragmatic and thus Despicable release.

The webPLM version is nice but too complex for my own need, so I
restart the dev of the plain old version. I hope to find a way to
merge both branches instead of having to choose the one to kill...

• Remove non-working features
  • Link identities (the target server was turned off)
  • "Call for Help" button
  • Switch Course (no course server anymore)
• Unclutter the interface
  • Remove the "load exercise" menu. Redundent with choose box, and
    not really useful anyway since no loadable exercise exist.
  • Restart for the last used exercise automatically
  • Display a "next exo" on success even if there is no child exo
• Fix broken features
  • Bug report should work again
• Pedagogical content:
  • Rewrite some exercises' mission text to fit in one page only

The Long Awaited release

  • French: missions and engine at 100%
  • Brazilian: missions at 100%, engine at 65%

  • #229: Poucet: Split the exercise in two. Both request to write
    two loops. The external loop is always a do/while ("until
    found"). The inner loop in the first one is a simpler for loop
    while the second exercise request the inner loop to also be a
    do/while (because of the corridors of differing lenghts)
  • InterleavedHanoi,SplitHanoi[123]; LinearHanoi,LinearTwinHanoi;
    TricolorHanoi[123]; CyclicHanoi; IterativeHanoi: New exercises
    to work on the decomposition of recursive problems.

  • Turtle: equal() was not detecting when lines are overlapping
    with no common extremities. We now detect when one line is
