Add NVMe temperature, fixes CPU temperature being in off state

[MaT1g3R]

Contains commits from #54

• Add NVMe temperature Doesn't pick up temperature from a NVMe drive #50 (source is named nvme//dev/xxx)
  • You will need to be able to execute sudo nvme without password
  • Possible way to do this:

  sudo visudo -f /etc/sudoers.d/nvme
  
  # /etc/sudoers.d/nvme
  $YOUR_USER_NAME ALL=NOPASSWD: /usr/bin/nvme

• Fixes CPU temperature goes to off state #53 by polling system monitor in ConfigTemperatures.qml

Recent kernels support nvme temperature through hwmon already. Is this project still maintained in general?
