Add custom scorecards generator

[maxidragon]

This PR adds a new tab to the "printing" section that allows users to print fully customizable scorecards. It will be very useful for unofficial events, as well as in various situations when it's necessary to print only one scorecard for a particular competitor

Looks great!

I didn't look at the UI code too closely, but as long as it gets the job done, it's all good :p

One UI nit: currently there is a lot of nested borders/boxes:

We should kill at least one level of nesting. I think what we can do is to have each section as its own card (rather than all sections wrapped in a single card). The "Add event" button can be below all cards.

(Also, I just pushed a fix, so there is a conflict in the scorecards code that needs to be resolved)
