Need API to create arbitrary records in NAME table

[puzrin]

As explainated in #86 (comment), users may wish to add more records to name table. But doing that via "named" options clutter API & code significantly.

We need something more simple AND "unlimited". At first glance, just pass array or desired records (but this should be discussed). What should be considered:

• Low level format.
  • Record can look like [ platformID, encodingID, languageID, nameID, string ]
  • Probably, string should be auto-encoded according to provided data
  • Probably, short variant [ nameID, string ] should be supported to auto-create 2 records for Win & Mac platforms
• Revisit named shortcuts
  • I would keep existing shortcuts only, and redirect the rest for "low level api"

Questions

• Should most of records be "duplicated" for Win/Mac platforms, or single platform (Unicode) is enough?
