resolves #80
Bump version to 2.0.9
Added CPU Info pulled from sysctl

Upon doing this I renamed CPU Speed to CPU Cores and removed the speed
as it is in the CPU Type field now.
Added Migration

Changed Schema in machine_model.php to 3 and added
003_machine_add_cpu.php to perform migration and add new column.
Removed duplicate < in machine_info.php
