[0.16.51] Victory screen shouldn't offer to save replay if unavailable

[Lizzy]

Repro steps:
1. Start new game without save replay enabled.
2. Launch a rocket.

Actual result:
Game offers to save replay anyway (and the file won't have any replay information).

Expected result:
"Save replay" is either not visible or disabled (with a tootip explaining why).

Thanks for the report. It's now fixed for 0.17.

Wow that was fast! I suppose it was simple enough.
