add start and stop idle command

[sorpdev]

Explaination

Implementation for my command suggestion (Issue #340)

manualIdleModeis to prevent automatically ending Idling when sendActivityis executed which has isIdling = false as default value.

The value of manualIdleMode is based on the setting Vscord › Status › Idle: Check.

manualIdling is used by the new commands and will override the isIdling parameter in the sendActivity function if manualIdleMode is set to true otherwise the normal behaviour will happen.

Command Stop Idle is only relevant if setting Vscord › Status › Idle: Check is set to false, otherwise it will automatically remove idle status

Use case

• For example if the setting Vscord › Status › Idle: Check is set to false, but you still want to manually set yourself to Idling
• You have a high Vscord › Status › Idle: Timeout but you know you're going AFK now and quickly set yourself to Idling

Feedback

I'm open for any feedback. Would love to see this feature implemented.
