Table improvements

[garrettjstevens]

• Add strand and phase
• Open table when feature is clicked (if not open already)
• Center "graphical" and "table" labels in the collapse bars
• Make collapse bars a bit more noticeable
• Improve start/end editing
  • try to disallow rich text editing
  • remove non-numeric characters in entered text before trying to submit the change
  • if there are no non-numeric characters, revert field to previous value, show an error, don't submit a change
  • when value is changed, make sure it is synced with the value in the client store
    • one way to do this could be to set the value back to e.g. feature.end in the onBlur, and then let the propagation of the change in the client store change it to the new value
