In a variety of places we're using boxes as data-modeling displays,
and in doing so we often want to either remove the children or
explictly destroy them.
Now ideally Gjs would support callbacks, and this would make using
the for_each functions possible, but even then these functions
are more efficient and shorter to type, at least.

Remove the StBoxLayout:spacing GObject property, and instead make
BoxLayout look up the spacing from the CSS style. This makes it
consistent with padding and will allow the use of units. (The
removal of the GObject property entirely instead of making it an
override is consistent with how we handle color, font, padding, etc.)

To each .c and .h file, add:
/* -*- mode: C; c-file-style: "gnu"; indent-tabs-mode: nil; -*- */
'gnu' is the default anyways for Emacs, but indent-tabs-mode is not,
so this sets things up to correspond to the policy of no-tabs.
