Less table row rerenders

[Arnei]

Improves table rerender peformance by

• Avoiding table row rerenders if possible, e.g. don't render rows again every 5 seconds if data has not actually changed
• Remove the hotkey listeners from the modals while they are not showing

How to test this

If you don't want to rely on feeling you'll have to use your browsers profiler to check if the rows are still all rendering one very poll. Note: the TableRows component will still rerender, this is about TableRow.
