Subject: [PATCH] Remove lastModifiedDate handling. (#300)

Several browsers used to implement a nonstandard lastModifiedDate property on File objects. This has been removed everywhere except Chrome, and it's not in the File API spec. This specification included special cases for keypath evaluation of that property name, and it wasn't tested. Remove the references.

Closes #215
