0031362: Inspectors - MessageView plugin for message alerts

- OSD_Timer in message alert,
- DumpJson correction,
- Selection owner should be dumped in selector. Sensitive entities might be used in the same owner, that leads to lots of the same dump in the result stream.

(cherry picked from commit e8bde810616e61cbe925981176681f2840234fa4)
