New setting watchViewReversed to place chat on the left

[TheLQ]

This has been a great mode in MultiView. After doing it manually for months, this implements it in /watch . Togglable in Settings.

Use case: Have 2 monitors. Left monitor is center, where my focus is, displaying other content. Right monitor to the side has Holodex. Chat on the left places it closer to my center of focus.
