Add optional constructor arguments to more Control nodes
This can be used to make editor code more compact.
However, as of writing, these constructor arguments cannot be used
from the scripting API.

This was already provided for Label and CheckBox, but it was missing
for other Control nodes where it made sense to provide a default value.
