SM52 essentially replaces JSRuntime with JSContext (though JSContext
itself was replaced with JSCompartment).
To prepare for this migration, rename all Runtime-related things to
Context.
Part of the SM52 migration, stage: SM45 compatible.

This was SVN commit r24181.
Caches the loaded mod versions, so that GetEngineInfo doesn't read the
zip and json files everytime and returns about 1000 times faster.
Adds two missing includes.
The lobby froze multiple times every few seconds on updateGameList().
The gamesetup page was slowed down with every stanza sent and the
load savegame selection page was slowed down per savegame selection,
proportional to the number of installed zipped mods.
