First step of the recording screen redesign. The screen is split into a fixed top part containing essential data and the peakmeters/triggerbar, and a bottom part that is in fact a list. The list contains the items that can be changed, and also some stuff that isn't important enough to be on the top part, like the filename. That filename is now shown completely. If the font is too big to have 6 lines on the display, sysfont is used.
