Added a --inplace flag to wx-config which will assume that it is

executing from the build directory and will then output -I and -L
flags to use the build directory copies of things.

 wx-config returns configuration information about the installed
 version of wxWindows. It may be used to query its version and
 installation directories and also retrieve the C and C++ compilers
 and linker which were used for its building and the corresponding
 flags.
+
+The --inplace flag allows wx-config to be used from the wxWindows
+build directory and output flags to use the uninstalled version of
+the headers and libs in the build directory.  (Currently configure
+must be invoked via a full path name for this to work correctly.)
