$toggle-checked-color doesn't work about pure-drawer

[mac81]

Hi Dave

Seems I've forgotten to add styling for the icon when checked.

Could you try adding:

.pure-toggle:checked ~ .pure-toggle-label .pure-toggle-icon:before,
.pure-toggle:checked ~ .pure-toggle-label .pure-toggle-icon:after {
background: #fff;
}

That worked, thank you. I modified it and added a PR to add one line to the global.scss to fix this in the future, so it will use the settings.
