Blinking tabs on realtime updates

- Now if a realtime update arrives, the tab numbers are recalculated
- The new (or updated) annotations' parents  are marked with the _updatedAnnotation property
- The new blinkBuckets() function in the heatmap checks for these annotations and does the blinking in the relevant buckets and removes that property (so only one blinking will occur)
- This new property is transferred via the bridge plugin
