2014 network limit 1.0a +utils +toc -doc -drmonero

commands and options for network limiting
works very well e.g. for 50 KiB/sec up and down
ToS (QoS) flag
peer number limit
TODO some spikes in ingress/download
TODO problems when other up and down limit
added "otshell utils" - simple logging (with colors, text files channels)

+/**
+@file
+@author rfree (current maintainer in monero.cc project)
+@brief interface for throttling of connection (count and rate-limit speed etc) 
+@details <PRE>
+
+Throttling work by:
+1) taking note of all traffic (hooks added e.g. to connection class) and measuring speed
+2) depending on that information we sleep before sending out data (or send smaller portions of data)
+3) depending on the information we can also sleep before sending requests or ask for smaller sets of data to download
