theme: Standardise text styles

Initial attempt to use standard text styles, in line with what's
being done for GTK (https://gitlab.gnome.org/GNOME/gtk/issues/1808).

This is just changing the sizes and weights for now. Spacing
adjustments will be required further down the line.

-## Animations
+## Getters, setters, and Tweener
-
-Most objects that are animated are actors, and most properties used in animations
-are animatable, which means they can use implicit animations:
 
+Getters and setters should be used when you are dealing with an API that is
+designed around setting properties, like Tweener. If you want to animate an
+arbitrary property, create a getter and setter, and use Tweener to animate the
+property.
 ```javascript
-    moveActor(actor, x, y) {
+    var ANIMATION_TIME = 2000;
-        actor.ease({
+
-            x,
+    var MyClass = class {
-            y,
+        constructor() {
-            duration: 500, // ms
+            this.actor = new St.BoxLayout();

+            this._position = 0;
