Fixing the 2.72 8M Issues

Unfortunately the “Wildcat” version sometimes still corrupts the 8MB usb disk when saving screen dumps.
Try to solve, but the BIOS::DSK::SectorSize() function doesn’t always return the same value.
So I moved to a fixed 8MB version and removed some of the “user applications” to get some extra RAM available.
Managed to get a stable working version.
On the way fixed some overflow problems in the “Spectrum analyzer” that sometimes crashed the application.
Also implemented the “probe gain” (1x,10x,100x,1000x) into the “measurements” and “cursor” screen.

(Note: this is only for 8MB versions!)

It doesn’t work on HW v2.81 like all the gabonator versions i tested. It corrupts the FPGA.
