minor Configure / makefiles updates

Removed mor (egcs) warnings
  Updated version to 2.0.1 in version.h
  Several corrections for strict compilers
  OpenGL updates
  new wxApp::InitVisual() for overriding in order to set non-default visual
    (unportable, of course)
  Added makefiles for DialogEd and Tex2Rtf
  made wxGTK compile with Tex2Rtf
  Added BEGIN_DRAG event to tree ctrl
  Added missing #include to lexel.l (unistd.h) (MSW?)
  new wxGTK.spec
  turned one or two more #ifdef into #if
