Sprite Show CheckBox Labels

[RobertBColton]

This fixes the show checkboxes on the sprite form so you can click the label to toggle the checkbox. I removed the second label and added the text directly to the checkbox. Then I used setLayoutDirection to put the label to the left of the checkbox like fundies had it. This does not affect the text layout direction according to the documentation so it should not interfere with i18n here.

This is great, until it turns out it breaks Arabic text layouts and now we need to update it.

1. Why is so much code required to create and maintain checkboxes?
2. Why isn't this handled by the ui file?
3. Can we wrap it in a helper to avoid needing to change fifty files later?

No, I have no idea why fundies wanted to put the label before the checkbox, but that's why it's so messed up. My other pull request moves this shit to the XML. Regardless, the way fundies did it with a separate label makes the label not toggle the checkbox. The way I just did it, with RightToLeft makes it always like Arabic, so regardless of the sprite form direction, the checkbox is always to the right of the label. Instead of deleting his extra labels, I could have connected them to the checkbox, but that's even more insane and doesn't help us.
