Title: Added Features: hide other users tracings, show nodes from adjacent sections

I added 2 new features:

1) hide other users tracings
- added per-user setting to either hide or allow viewing of other users tracings
- added db migration script

2) show nodes from +/- N adjacent sections
- modified db query
- modified tracing tools ui
- modified some js ui calls to allow drawing of nodes with larger zdiffs
