M cell.cpp - improved the ChrRepairDistrLocally() to:

				- do dilation around overcrowded points correctly
				- do it within the limits of the maskNucleus
				- than erode by 1px to get further from the maskNucleus boundaries
				- insert not-overcrowded points as additional constraints to
				  account for when choosing new distribution for the overcrowded points

M    cell.h		- ChrUpdateStats() now takes a new parameter: the percentil,
			  which is used when computing Cell::chrSpreads
M    cellChr.cpp	- implements the changes in the ChrUpdateStats()
			- added a new macro REPORT_CHRDOT_DISTRIBUTIONS_IN_ChrUpdateStats
			  that can report chromosome territory distributions for gnuplot
			  (the macro is not controlled from the Cmake, at least not yet...)

M    cellScm.cpp	- added macro-guards to get rid of a compiler warning
M    scheduler.cpp	- corrected English in some debug messages
