ncurses 5.9 - patch 20140809

+ modify declarations for user-data pointers in C++ binding to use
  reinterpret_cast to facilitate converting typed pointers to void*
  in user's application (patch by Adam Jiang).
+ regenerated html manpages.
+ add note regarding cause and effect for TERM in ncurses manpage,
  having noted clueless verbiage in Terminal.app's "help" file
  which reverses cause/effect.
+ remove special fallback definition for NCURSES_ATTR_T, since macros
  have resolved type-mismatches using casts (cf: 970412).
+ fixes for win_driver.c:
  + handle repainting on endwin/refresh combination.
  + implement beep().
  + minor cleanup.
