What's new in this version:

Main:
- Fixed: A lingering process was present when you tried to start OCCT twice

Monitoring:
- Added Snapshot polling support. This allow HwInfo to more accurately get the CPU frequency and uses much less CPU cycles to do so. Enabled by default.

Linpack:
- Fixed: During stability certificates, errors were properly detected and reacted upon, but failed to show in the log and indicator
- Fixed: error count in the log would repesent the total numbers of errors detected and not the new error count

Memory:
- Fixed: Final fix to the GUI slow updates during Memory stress tests

Enterprise:
- Fixed: when maximized, the test names were missing from the period display. What a weird bug to be honest.
- When a single period is present in a schedule, the delete and move buttons are now hidden (they didn't do anything anyway)
