Submission can now generate a temporary excel file that contains the
entire action log for a submission. Implements VIR-15.
+ Submission.getAttachmentsByType(AttachmentType.ACTIONLOG) will get
this Attachment object generated. The actionlog xlsx file within the
attachment needs to be explicitly deleted when the actionlog file is
done being used. Otherwise it will linger in JVM's tmp directory until
Vireo is stopped.
+ ACTIONLOG AttachmentType was added as an exporting file option to
FileExport and ExcelPackageExport. FileExport now also exports all
attachment types.
