destination file name prefix

The following patch adds the possibility to set a file name prefix for the destination files. The prefix will be added to the file name of all uploaded files. The prefix is entered by appending it to the destination bucket name in the bucket name field. E.g. ‘mybucket.example.com/builds/${BUILD_NUMBER}’.
