Commit Summary

7ec2cf25 Refer to the tutorial instead of X.D.Extending more often

Essentially, whenever the tutorial actually has decent material on the subject matter. The replacement is roughly done as follows:

• logHook → tutorial
• keybindings → tutorial, as this is thoroughly covered
• manageHook → tutorial + X.D.Extending, as the manageHook stuff the tutorial talks about is a little bit of an afterthought.
• X.D.Extending (on its own) → tutorial + X.D.Extending
• layoutHook → tutorial + X.D.Extending, as the tutorial, while talking about layouts, doesn't necessarily have a huge focus there.
• mouse bindings → leave this alone, as the tutorial does not at all talk about them.

09c47c2c X.A.FloatKeys: Add direction{Move,Resize}Window

These are simpler, more easily understood, alternatives to the existing functions.

Fixes: https://github.com/xmonad/xmonad-contrib/issues/712

180a4aa8 X.H.InsertPosition: Add combinator

Users may not see the warning that insertPosition definitely needs to be inserted at the leftmost position, which can cause undesired behaviour. Having a combinator that handles this automatically seems like a sane idea.

Fixes: https://github.com/xmonad/xmonad-contrib/issues/709

   (Note that `docs` wasn't changed since it already inserts itself
   rightmost.)

84c94d83 X.A.Navigation2D: More prominently document strategies

Also, add a note that users who use gaps or spacing may need to look into these strategies a bit more deeply.

Fixes: https://github.com/xmonad/xmonad-contrib/issues/627

f833d949 X.A.Navigation2D: Add sideNavigation as to default tiled navigation

Add sideNavigation as a fallback if needed. This should not have any user-facing behaviour change when not using gaps or spacing, as line navigation is preferred. However, users who do use spacing or gaps should now potentially not have to change the default strategy in order to have a usable module.

Checklist

• [x] I've read CONTRIBUTING.md

• [x] I've considered how to best test these changes (property, unit, manually, ...) and concluded: most of this is docs, but I've manually tested e.g. the changes to FloatKeys.

• [x] I updated the CHANGES.md file

  Where appropriate.
