optimized character representation setting

* Esp. with the new Scintilla version, the representation
  setting as part of every SCI_SETDOCPOINTER has turned out to
  be a performance bottleneck.
* The new Scintilla has a custom tweak/patch that disables any
  automatic representation setting in Scintilla itself.
  It is now sufficient to initialize the SciTECO-style representations
  only once in the lifetime of any view.
