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 darcs-hash:20071130205430-f49a6-0ff042af60c91416fd8dd8190cbd9022bcabb269.gz
