Small StopDesign updates

Just a few small updates to make it easier for anyone using StopDesign theme to know what does what and a few updates to make page loads and theme size a bit tinier, as well as bring code a touch closer to modern standards by dropping IE6 work-arounds used because it did not support transparent PNG files.

Also just a small update to the comments and technical documentation for the GoogleMaps extension. No code changes. (Mostly I read books but I wrote enough technical documentation that it is kind of a bad habit to read files every now and then...)
