My board was designed using different libraries and I've discovered 9
different drills! .5;.7;.8;.81;1.00;1.02;1.27;3.00,3.60
It's clear that we can simply discard .81 and replace it with .8,
1.02->1.00 e.t.c.
I've made a simple utility which makes the following actions:
1. Read your .cfg file with "min...max" ranges and new values
2. Replaces all occurences in the .brd file choosen
Take a look at screenshots "before" and "after". Between pictures is
.cfg file in form: "min1,max1,new1;min2,max2,new2..."

P.S. Soon I'll make a documentation, "nicer look" and publish it.
P.P.S. Next version will also replace "pad sizes" and "via sizes"
similar way. Major bonus - it modifies .brd file, so later RUN DRC!!
I'm waiting for your feedbacks and requests.
