openhardwaremonitor

Fixed an OverflowException when trying to use (unsupported) 64-bit thread affinity masks on 32-bit systems.

Fixed the following issue (present only on 32-bit systems):

Fixed Issue 651.

Changed the settings save code to use a two file based approach in order to reduce cases where settings are lost or reset (Fixed Issue 501).

Added a new "Undefined" control mode. Changed the GPU fan control to restore to default (auto) settings when the Open Hardware Monitor closes (unless the control remained in "Undefined" mode).
