Small improvements to on-screen use only. CLI -B and GUI 'B' to toggle
boxes around stats. CLI -^ and '^' to change units for Disk I/O KB/s ->
MB/s -> GB/s. This happen temporarily too if the size of the statistic
will not fit on-scree. Code changed to ensure clean compile for GCC 12
which does extra checks but got confused by some perfectly good C code!
Note: updated makefile makefile
