Briefing text is too spaced out

[BorderKeeper]

It is hard to read briefings if they are spaced out so much. Each line looks like a new header.

The spacing here is actually identical to ARCHUB V1 (although in V1 the font is smaller)

For V2 I've taken the approach of not modifying any of the briefing HTML (in V1 any font sizes were replaced with bold tags, headers were resized, etc) to try to make the briefing on the site representative of the briefing in game - some of the headers will look massive in V2 since old missions all used font size 18 to be compatible with V1

The reason these spaces are so large is there are 2x <br> tags being used, so I'd be interested to know whether the line spaces are also that large in game before adjusting anything
