Simple Quest System + UI 1.0

Useful. Actually Is compatible in v17.2, however:
1. There is a syntax error (you'll be notified when you add it to your game, there's a double close parentheses somewhere)
2. Unless you're an intermediate user, it is not immediately obvious how to add this to the pause menu (which I have managed to do)
3. advanceQuestToStage is no longer working and I cannot see how to fix it. Otherwise quests work as intended
4. If you have NO active quests, the game breaks. so you'll need to restrict its access in the pause menu on the basis of hasAnyQuests? , and never let the player complete all active quests - should always be one ongoing quest.

This is a really good quest system, only thing is: you should explain the How to Use section in more detail, like how do I set up "advanceQuestToStage(questID, stagenum)" <- questID the name of the quest, but what do I write on stagenum? that kind of explanation would be neat!

awsome feature bringing some changes and effects to the game

Good quest system and easy to use though I haven't tested all feature yet it's not giving any error.
