BS1770demo improvements:
a new RMS option disabling the gating function for background noise measurement,
the handling of the edge case where all gating blacks are below -70 LKFS,
improved reporting with scaling factor being reported in the linear and log domains.
WMC Tools updates:
New command line parameter to allow control on the number of frames per second (default still 50)
Export information on all memory allocations occurring during runtime
Example script for graphical analysis and profiling of dynamic memory allocation
Bugs fixes and code improvements
