Added new features:
1. Read sensor memory without triggering temperature conversion. Just read 'w1_read'
file instead of usual 'w1_slave' file.
2. Ability to simultaneously trigger temperature conversion on all sensors in the network.
Reading the 'w1_convert_all' file on any temperature sensor in the w1 net will start
temperature conversion on all sensors in the w1 net.
So it is possible to greatly speed up sensors reading on the big 1wire nets by starting simultaneously temperature conversion on all sensors and then reading results from the sensors memory.
