"mode" attribute in the audit log breaks Panorama upload

[rita-gwen]

I tried to run a random Skyline tutorial (Small Molecules) and upload the resulting file into Panorama and it breaks on a new audit_log_entry attribute. In this case the attribute is mode for the small molecule document, but the general problem is that Skyline has no well-defined schema for the audit log structure it produces while Panorama expects the log file to conform to a schema because the audit log class database structure depend on it.
We need either to limit such additions/modifications to a necessary minimum or revise the way Panorama stores the audit log.

It is also not clear why this attribute was placed at the log entry level. It seems to belong to the document and accordingly it should be at the log root level.
