Version 1, Update 84

• null is now supported for the variable field in setBoundVariableForPaint, setBoundVariableForEffect, and setBoundVariableForLayoutGrid. Passing in null will detach the bound variables.

• For plugins that can run in VSCode, we now recommend replacing alert() and confirm() dialogs in the plugin UI with custom UI, since VS Code blocks native dialogs. The Working in Dev Mode page is updated accordingly.
