British and South African updates

To reduce the number of blog entries for minor updates, I'll start to combine them when I can. Here's some minor updates for the following:

• South Africa: Marmon-Herrington

• United Kingdom: Crusader Mk I, Valentine Mk II, Universal Carrier, Cruiser Mk II

South Africa's Marmon-Herrington armored cars updated

Marmon-Herrington imported parts from Britain, Canada, and the United States to produce its Marmon-Herrington armored cars. I've reorganized the page and added additional historical information.
