Pokemon Emerald: Temporary fix for missing items

[Zunawe]

What is this fixing or adding?

Adds a delay to the client's game watcher loop if the client has to update its item handling. If the response from the server that includes a player's own items doesn't come before the watcher starts giving the player items, they may be receiving the wrong items and some of the items they should have received may be skipped.

Bug is more likely to occur in the middle of an async when the player reconnects after many items have been found, and is more likely to skip items if there are many players, since the Emerald player is unlikely to find items for themselves.

The actual fix is to add the information into the patch file and read it before sending the first Connect, but I don't have a place for it yet. That change will be made when the patch is next updated.

How was this tested?

Opened a patch using remote_items with the client and received a few items. Wasn't able to reproduce the issue, but this fix is only adding a safety buffer to avoid a race condition anyway.
