Lute v3

This is a minor version bump (from 3.2.7 to 3.3.0) because Lute now creates “status 0” terms for any page opened for reading. These terms are effectively “pending terms” that the user processes as they read. This change fixes some parsing inconsistencies, and allows for import of “status 0” terms as unknown terms.

• #327: autofocus to term input box for new terms. By @imamcr in #368.
