Hi

as an extra funny feature, I added a "blitter-o-meter" to the status bar.

Depending on the blitter's usage during each VBL (from 0 to 100 %), the 
blitter's led will be filled with a lighter color.

For example, check "We Were" or the latest DHS demos (Sea of colors, 
....) to see it in action.

This is only for the SDL UI version, someone will need to add it to the 
OSX version if people want it too.

By the way Anders, while checking Sommarhack 2017 invitation demo in 
mega STE mode, I noticed the blitter-plasma part is shifted. Is this 
supposed to work on real mega STE, or is this what the readme meant by 
"the plasma is eight pixels shorter every scanline, due to a slower 
blitter" ?
