Add competitor's personal record to scorecard

[maxidragon]

Quoting comments from a post on Cyoubx's Friends:

When I'm judging, I would love to see a competitors, single and average printed on the scorecard so you can know what they would be happy with

that'd be helpful for competitor too so they'd know if they got a pr or not w/out checking online

If you don't mind, I'd be happy to submit a PR

Hey, I can see this being a nice addition, but at the same time I'm not sure there's enough space left on scorecards to reasonably accommodate this. Adding too much additional information may confuse some people, for example an unexperienced judge (a non-competitor) would need to understand the meaning of more numbers: cutoff, time limit, best average, best single.

Basically, I'm open to design changes, I'm just not convinced this addition brings enough value in a general case.
