- improve dynbuf implementation further
- save now saves shstrs longer than HUGE_BUF, lets fix any brokenness remaining
  in the server...
- converted most describe_*-functions to dynbuf_text, making them likely
  faster (or maybe slower), while removing any hardcoded length limit.
- memory allocated for static dynbuf's is not being returned ever (at least
  not the initial chunk, maybe fix this?)
- implement framework for predeclared const shstrs for comparison purposes
  (shstrinc.h).
- enabled and enforced new material code.
- implement hack to clean up book titles.
- increases HUGE_BUF to 10240, to be similar to mac network packet size.
