Bugfixes

• Spawn tasks on individual threads
• Don't force a default of fan-curve on reload
• Add missing profile commands

Bad behaviour in fan-curve new function that was forcing a re-init to default on reload. Remove this and only save config again after loading the config file and writing a curve (hidden side effect of write is that a zeroed array is defaulted to read-from-system - this needs to be changed too).

Closes #140 (closed), #139 (closed)
