Added thermal, cpufreq and coretemp monitors.

Prerequisities:
thermal
- thermal module should be loaded/compiled in kernel
- available in (at least) intel centrino processors
cpufreq
- acpi_cpufreq module should be loaded/compiled in kernel
- available in modern processors
coretemp
- coretemp module should be loaded/compiled in kernel
- available (at least) in core 2 duo processors
