rewritten View and Interface base classes using the Curiously Recurring Template Pattern.

 * without the one-view-per-buffer designs, many Scintilla send message (SSM)
   calls could be inlined
 * with the new design, this was no longer possible using the abstract
   base classes. the CRT pattern allows inlining again but introduces
   a strange level of code obscurity.
 * tests suggest that at high optimization levels, the one-view-per-buffer
   design and the CRT pattern reduces typical macro runtimes by 30%
   (e.g. for symbols-extract.tes).
 * only updated the NCurses UI for the time being
