1.3.0

• Perform fewer memory allocations in MMDB_get_entry_data_list(). This
  significantly improves its performance. GitHub #147.
• Fix mmdblookup's build epoch reporting on some systems. Big endian
  systems with a 32-bit time_t no longer show a database build date of
  1970-01-01 00:00:00. Pull request by Rainer Jung. GitHub #143.
