#282: python path getting overwritten

 In %OSGEO4W_ROOT%\bin\o4w_env.bat the \etc\ini\*.bat files are called in a
 loop (alphabetically i presume). When %OSGEO4W_ROOT%\etc\ini\orfeotoolbox-
 python.bat gets called, it sets PYTHONPATH to
 %OSGEO4W_ROOT%\apps\orfeotoolbox\python. This gets overwritten when
 %OSGEO4W_ROOT%\etc\ini\python.bat is called afterwards i.e. SET

 This causes QGIS to report an error on startup ("Could not find the Python
 bindings for OrfeoToolbox, which are required to run the this module") and
 breaks the python bindings in the osgeo4w shell generally.

 Perhaps these batch files should set PYTHONPATH by appending/prepending,
 i.e. for etc\ini\python.bat:

 IF "%PYTHONPATH%"=="" (
     SET PYTHONPATH=%OSGEO4W_ROOT%\apps\Python27
 ) ELSE (
