Why this PR

• Waits stats by hours is more interesting than global waits stats so i switch to this view by default
• Adding day boundaries help to see when things happened
• Adding the avg waittime ratio will help to see how much the wait are importants without needed to use tooltips
• I switch the wait ratio units to something more human readable
  • ms/sec under 1
  • sec/sec between 1 and 60
  • min/sec above 60
