Applied patch [ 605592 ] Unicode patch for dirctrlg.cpp

Markus Greither

 just compiled the wxWindows CVS trunk using
BCC5.5.1 and UNICODE. I noticed a small bug in
girctrlg.cpp, that prevented compilation. There are more
such glitches in the wxGrid, but as I was running out of
time, I disabled this for now. Otherwise, compilation
worked fine and I was able to run the minimal sample
(using UNICOWS on my WIN98SE).

(I also corrected some wxGrid Unicode string typos -- JACS)
