1. new wxFFile class - as wxFile but uses fopen/fread/fseek... instead of

open/read/seek...
2. wxTextCtrlBase appears, several bug fixes in MSW wxTextCtrl and made
   LoadFile() behave in the same way under GTK and MSW (fixed it for MSW
   too)
3. Corrected the sash position calculation in sashwin.cpp - seems to work
   now but I wonder how it could ever work before?
4. new, tmake generated, MSW makefiles. They probably don't work - will fix
   them as soon as people start complaining.
