Subject: [PATCH] st/entry: Unset key focus when made unreactive

It seems reasonable that an entry shouldn't allow entering text when not
reactive. The same could be achieved by changing the text's :editable
property, however that will disable scrolling if the text doesn't fit,
which may result in an unwanted size change.
