Create checksum file of same name when all selected files share the same name

[redactedscribe]

Currently, if only one file is selected when creating a checksum file, the suggested file name is that of the selected file. If more than one file is selected when creating a checksum file, the suggested file name is instead "checksums".

It would be nice if HashCheck would check whether all selected files share the same name, and if so, suggest the same name for the checksum file, else suggest "checksums".
