CLONE - Logout IDE from PLC after configurable time of inactivity

Fixed [[GENERAL]]
Added new option page "Online"
* New Setting "Force disconnect from device after time of inactivity"

Added new startup parameter "ForceDisconnectAfterInactivity", which overrides the new setting:
* --ForceDisconnectAfterInactivity="2000" (Will perform a force logout after 2000 seconds of inactivity. The specified time will be clamped to the range of 10-10800)
* --ForceDisconnectAfterInactivity="0" (Will disable the new setting)

Note that the inactivity is tracked by mouse/keyboard events that are local to CODESYS. This means that CODESYS running on a second monitor will force a disconnect even if the user is busy typing inside another application on the primary monitor. However, simply moving the mouse across the CODESYS UI without any clicking will reset the inactivity.
