Random quest ID

[KatatsumuriPan]

Now newly created quest ID will be random.
This prevents merge conflicts when multiple people try to add or remove quests simultaneously.

Changing the type of quest ID from int to UUID is pending for compatibility.

I won't apply this change to quest-line ID and other IDs until #103 is merged.

problems:

• similar logic should also apply to questlines
• since the questID is absurdly long now, should change PanelButtonQuest.java:103 to not display the questID, regardless of if advancedInfo is enabled
• again, absurdly long so it should be less publicly visible, should change EventHandler.java:142 so sharing the quest to chat doesnt include the questID.
• really long, want an easy way to copy - GuiQuestLines.java:354 is the place where we get the popup for "Share to Chat", should add an option below that for "Copy ID" which copies the quest ID to the clipboard

question:
what is the logic that leads to continuing to use an int instead of switching to using a UUID, as was done in GTNewHorizons#89?

I think the only advantage of UUID is their randomness.
Considering the cost and trouble, I don't think there is any benefit to changing to UUID.

Closing in favour of #113. Thank you for all the work!
