updated Scintilla submodule: fixed threading/deadlocks in Gdk earlier than 3.6

 * I fixed up the earlier commit a2b4a4cf4dfe7f7d72eeea566290f9ec51be7dbb.
 * For Gdk >= 3.6 there are no functional improvements/fixes.
   However older Scintilla Gtk builds would have been broken by the
   last Scintilla patch. This is of course important when contributing the patch
   to the Scintilla community.
