Feeling around a bit more..... there's not really any precedent for a ui model,
nor an app list model, to be a struct. Convention is class + accessors. Any
thoughts?

Hmm. I don't think this even belongs in this folder... The models here are
highly abstracted UI components rather than actual ui.

I think it's worth moving this to its own folder ui/base/profile_selector given
that we will be needing more shared assets for the new profile selector.

+    AvatarMenuItemModel(size_t model_index, const gfx::Image& icon);

Looks like you got carried away with the indent here :p. 4 spaces -> 2 spaces.

[calamity, 2013/08/01 08:35:45]

Done.

+    ~AvatarMenuItemModel();
+
+    // The icon to be displayed next to the item.
+    gfx::Image icon;
+
+    // Whether or not the current browser is using this profile.
+    bool active;
+
+    // The name of this profile.
+    string16 name;

base::string16 for these I think

[calamity, 2013/08/01 08:35:45]

Done.
