Limit height of code blocks

[pierres]

Users often post lengthy code or configuration listings which makes following the actual discussion difficult. Therefore we limit a code block by half a screen while still being able to scroll through the code listing itself.

Thank you! I've wanted this done for a while 😍 gets hard to scroll when people post logs.

@SychO9 Double-check you're happy with the compatibility change I made, otherwise good to merge 👍

Thank you @pierres!

[SychO9]

@davwheat fine by me 👍

[davwheat]

Ohh hold off a moment... LESS doesn't like max

[davwheat]

Tests should pass now... 🤞

I always miss that when using vanilla CSS functions, LESS almost always has the same functions implemented that calculate the result when compiling.

[davwheat]

Me too. It's a real pain 😕

Thanks a lot. Next time I'll try not to forget about LESS and older browsers :-)
