v1.3

• Changed method to generate the machine uuid for ocsinventory-ng:
  We use the system uuid (or the mac address, if the former is not available) and the bios release date.
  If you were using an older release of the agent, this will create a duplicate inventory (again).
  This should be hopefully the last time this happens, as this method seems to be more reliable.
• Completely reworked the way we retrieve info about the machine:
  Use the /sys/devices/virtual/dmi tree, if it's not available, try dmidecode, then lshw.
  Integrate the various info in a better way and made the code more robust.
• Improved inventory of memory slots: added slot number and description. Also: made it work in more cases
• Improved cpu identification: added number of cores, avoid adding an entry for each core of multi-core processors.
  In most cases, at least.
