Subject: Add support for adding a note to a key binding (with bind-key -N) and
 use this to add descriptions to the default key bindings. A new -N flag to
 list-keys shows key bindings with notes rather than the default bind-key
 command used to create them. Change the default ? binding to use this to show
 a readable summary of keys.

Also extend command-prompt to return the name of the key pressed and add
a default binding (/) to show the note for the next key pressed

Suggested by Alex Tremblay in GitHub issue 2000.
