Rustlings 5.0.0

Probably Rustlings' biggest release yet! 🎉
For detailed information, check the changelog. I'll post the features section here:

• Hint comments in exercises now also include a reference to the
  hint watch mode subcommand.
• intro1: Added more hints to point the user to the source file.
• variables: Switched variables3 and variables4.
• Moved vec and primitive_types exercises before move_semantics.
• Renamed vec to vecs to be more in line with the naming in general.
• Split up the collections exercises in their own folders.
• vec2: Added a second part of the function that provides an alternative,
  immutable way of modifying vec values.
• enums3: Added a hint.
• Moved strings before modules.
• Added a strings3 exercise to teach modifying strings.
• Added a hashmaps3 exercise for some advanced usage of hashmaps.
• Moved the original quiz2 to be strings4, since it only tested strings
  anyways.
• Reworked quiz2 into a new exercise that tests more chapters.
• Renamed option to options.
• options1: Rewrote parts of the exercise to remove the weird array
  iteration stuff.
• Moved generics3 to be quiz3.
• Moved box/arc exercises behind iterators.
• iterators4: Added a test for factorials of zero.
• Split threads1 between two exercises, the first one focusing more on
  JoinHandles.
• Added a threads3 exercises that uses std::sync::mpsc.
• Added a clippy3 exercises with some more interesting checks.
• as_ref_mut: Added a section that actually tests AsMut.
• Added 3 new lifetimes exercises.
• Added 3 new traits exercises.

Summary

This release adds 12 new exercises, makes tons of little (and sometimes significant) improvements to existing exercises, rearranges a good chunk of the exercises to make more sense in our curriculum (while still trying to stay faithful to the book), and it gets rid of some exercises that have not been a good fit for this project.

There's still a fair amount of things that I want to change, such as having better exercises for smart pointers, but that's for a future release. Feel free to post your feedback after you've completed this new version of the course!

Special thanks for the Rust Foundation for sponsoring the majority of my work on this release!
