Get errors from batch file upload

[JTremblayAGT]

It would be nice to have an override of the ftp.DirectFileHandling.UploadFilesToController method that also gives access to the error messages for each file that failed to upload (program in use, error during load, write protected, etc.). Right now it only returns a list of the files that successfully uploaded which forces the users to look on the robot controller for errors.

Good point, the same applies to downloads.
We'll see how we implement this, as it's not possible to have the same method prototype with only the return type changing.

Perhaps an optional OnError(file, exception) delegate passed as argument would be a nice solution? it would leave error handling
to the user and (hopefully) not be too much work to add to the existing implementation.
