Fixed Table's use of deprecated isAccessible, finishing parseInto.

Fixed the Table's use of the deprected isAccessible, finishing the parseInto method in the process in order to test taht the new implementation is "correct". Note that there is not a published API for this method on processing.org so it is unclear if the interface's intended behavior was maintained. See https://processing.github.io/processing-javadocs/core/processing/data/Table.html#parseInto-java.lang.Object-java.lang.String-.
