Feature/split triggers into categories

[tommai78101]

There are 3 categories:

• Regular triggers (Game Triggers). These triggers are what the player will be interacting with when the player wants to investigate in-game obstacles. These triggers are usually repeatable.
• NPC triggers. These triggers are what the player will be interacting with when the player wants to speak with NPCs.
• Event triggers. These triggers function as in-game events, or plot devices. Unique events that will only occur once in the game will happen here. These triggers are non-repeatable, and whatever flags they trip in the game, will be saved to the game save data when the event has completed.
