Crowdmap updates should save and then reapply room marks when updates occur.

The crowdmap is a massive boon to those who don't - or won't / can't - map games on their own, but it does mean that the use of room mark is somewhat limited. If you make your own marks on the map, they're lost when a new update is released.

I'd suggest that an update be made to the update fetching / installing script to store marks in a table before the latest update is downloaded / applied, and then said table is used to apply marks once the update registers as successful.

One thing to consider when/if this is ever implemented is that sometimes things change IG and room marks should be removed...best example is when all of the denizen commodity shops shut down so in the crowdmap we removed all the shop $ signs. I've seen a number of normal denizen shops get changed/moved over the years too.
