Restore antRun.bat for Win9x users. This should allow the exec task to execute on Win9x. I have changed Glen's patch to test for platfrom != NT rather than == 98 so it will support 95.
NOTE: There is an important limitation. Only 9 arguments can be passed to the command being exec'ed when the antRun.bat file is used. This should only occur when the directory is not . and the platform is not NT. This was the original reason this was changed (and antRun.bat) deleted.
