The previous asynchronous approach did not work particularly well,
leading to large janks when switching to custom maps or opening the
mission browser.
This commit introduces two key changes:
* Rule loading for WorldActorInfo and PlayerActorInfo is made
synchronous, in preparation for the next commit which will
significantly optimize this path.
* The full ruleset loading, which is required for map validation,
is moved to the server-side and managed by a new ServerMapStatusCache.
The previous syntax check is expanded to include the ability to run
lint tests.
As far as I could tell, this was the last place that still
used 'seconds' instead of ticks, apart from
some sound notification intervals (which are better
converted to real [milli]seconds).
Also renamed ScaredyCat.PanicLength to PanicDuration for
consistency and easier finding.
Both writing to perf.log frequently as well as GetTimestamp
aren't free and hurt performance particularly on slower systems
(which can have notably higher output to perf.log, further
amplifying the problem).
Therefore we make simulation perf logging opt-in.
Additionally, logging of the current tick and tick type
(local/net) is removed from debug.log, and some
remnant debug logging for kills and pips is removed
to keep performance-sensitive logging limited to
perf.log.
*Remove internal GameSpeed defaults
Enforce setting values explicitly all the time
Require definition of a DefaultSpeed
*Remove Global.Timestep default
*Remove the hacky Timestep/OrderLatency setting via LobbyInfo
*Fix shellmaps ignoring mod-defined gamespeeds
*Make DateTimeGlobal use the MapOptions gamespeed
* ResourceType trait has been removed.
* Simulation-related data is now defined on the
ResourceLayer (which mods can subclass/replace).
* Support non-money resources by moving the resource
values to the PlayerResources trait.
* Allow mods to disable the neighbour density override
and instead always use the map-defined densities.
* Allow mods to define their own resource placement
logic (e.g. allow resources on slopes) by subclassing
(Editor)ResourceLayer.
* Improve ability to subclass/override ResourceRenderer
by exposing more virtual methods.
