How to fix getFileList

When you use the MEL command getFileList, make sure there is a trailing "/" on the folder string you pass to it. Otherwise the command returns the folder string you passed to it initially.

string $imageDir = (dirname (`fileDialog`) + "/"); // Stroke must be added
string $fileList[] = `getFileList -folder $imageDir`;

This was a frustrating bug and hopefully this will show up in search results when someone else has this issue.
