Random maps don't report name

[Philip Taylor]

session.js has reportPerformance which uses Engine.GetMapSettings().Name to say what map the profiling data applies to. When playing random maps, the Name seems to be undefined. I expect it would be best if that was the name of the random map script, and maybe reportPerformance should report the size and seed too, so we could (in theory) detect whether certain maps have significant performance problems.

The first part is easy to fix. But what do you think about using the initData that gets passed to sessions instead of Engine.GetMapSettings()? It doesn't return all the data, like map type. Map type could be tested for "random" and in that case, the seed and map size could be included.

That sounds sensible - I'm happy with any method that returns enough data to identify the map.
