Base info QoL improvements

For now it is better to start simple.

Don't disagree. Was just an idea what might be useful to display at a time when the player doesn't even know such huge UFOs exist.

Come to think of it, one could also only calculate based on the biggest UFO uncovered in the pedia, and/or the biggest that has assaulted a base so far, but that's also no longer 'simple'.

That I do.

Didn't see that, but good.

Should be in PR by now.
