Feature: Consolidate Next Transition actions

[arikorn]

In my struggles to make clear names for the various next transition/on air action (and feedback, to a lesser extent), I've come to the conclusion that consolidating them into two actions should make things clearer and more consistent:

Action 1: 'Next Transition: Set "next" status (KEY, DSK, BKGD)
Options:
Layer: KEY, DSK, BKGD
Action: On, Off, Toggle, On PVW, Off PVW.
Description: 'On/Off/Toggle is equivalent to pressing the button on the GoStream, so its consequence depends on the state of "On Air", the last two options ensure that the behavior in PVW occurs independently of the state of "On Air"'

(N.B. the last two options will be disabled if BKGD layer is selected.)

Action 2: 'Next Transition: Set "On Air" Status'
Options:
Layer: KEY, DSK
Action: On, Off, Toggle, On PGM, Off PGM.
Description: 'On/Off/Toggle is equivalent to pressing the button on the GoStream, so it will affect both PVW and PGM, the last two options ensure that the behavior in PGM occurs independently of the state of the "Tie" button'

If approved, this will be included in my PR on Next Transition actions (#45, #54, #55, #66, etc.)

agree with this. BUT these action should start with "MixEffect" not "Next transition" ....
And the old actions controlling these keys should be marked deprecated regardless of their current working status
