#TTP 335685 - EDITOR: Level Browser: Allowed to click "move selected actor to level" on an actor that is already in the selected level
#branch UE4
#proj Editor.WorldBrowser
#proj Editor.Levels
#change Added a new method IsValidMoveActorsToLevel to both FLevelCollectionModel and FLevelCollectionViewModel, this is used to enable the Move Actor to level command for both cases. It scans the selected actors and checks their levels against the selected levels. If any actor is contained within any of the selected levels it disables the control. It also disables the control should there be no actors selected. If both of these cases pass it simply checks if the level is editable.

Breaking changes include:
* Rename of GEditorModeTools -> GLevelEditorModeTools to signify that it applies only to the level editor modes
* Addition of FEditorModeRegistry, responsible for managing and creating new editor modes. Modes are no longer registered with an instance of the mode, instead with a mode factory that is able to create a new mode of that type.
* Editor modes now operate on FEditorViewportClients rather than FLevelEditorViewportClients
* Added ability to specify an FEditorModeTools when creating an FEditorViewport
Moved component vizualiser manager handling outside of individual editor modes, and into FLevelEditorViewportClient. This should make it easier to transplant in future.
This work addresses TTP#334640 - EDITOR: Investigate making editor modes a per-'editor' concept
