Competition match view shouldn't use pencil icon

A pencil icon typically indicates that you're editing something typically lightweight (name, ancillary metadata, etc.)

With the view presented here, when I click that pencil icon for a row in the match, I'm presented with way more options that don't necessarily convey the message that this is 'editing'. I think a couple of options could be made here:

- Use an icon like a clipboard, target, or plus icon, or a play icon
- The entire row should be clickable to get this view
- When a match is scored, there should be another check box indicator or otherwise to show that the match is scored and finalized
