Synchronization code is now printed at the end of each test. The code is
either loaded from uci config file or - if missing - downloaded from the
control server. When uuid is chanded the sync code is automatically
flushed and prepared to be regenerated.
	The process is divided into two functions:
load_sync_code: checks the uci for the code
download_sync_code: download the code from the control server

Some minor changes were done:
	-uci set commands produce no explicit error messages from now on
	-new colored info printouts were added - these inform the user
	that some config is missing and is dowloaded or generated

A new option was added that allows the user to download history of
past speed measurements. These measurements would be stored in /tmp/

Option that allows the script to wait random amount of time up to N seconds
before the test starts added.

Otherwise it doesn't work on OpenWRT.

This script communicates with netmetr control server
and starts rmbt client with received parametres.

Thanks to James Marsh for figuring it out.

And some shell simplification.
