Rename softWrap to softWrapped

Our new pattern for booleans is to have ::set and ::is, and that means
the property name needs to be in passive voice for ::is to make sense.
This is in preparation for adding a new change observation method.

* ::setSoftWrapped
* ::isSoftWrapped
* ::toggleSoftWrapped
