v5.6.2 - Sub-objectives, & much much more!

• [+] NotQuests now supports sub-objectives! Each objective can have unlimited sub-objective. And each sub-objective can also have unlimited sub-sub-objectives.. and so on!
• [+] You can now set a delay for conversations, e.g. if you want conversation messages to appear half a second later to give it a more natural feeling. You can set it category-wide, conversation-wide, speaker-wide or for just a single conversation line
• [+] New NPC System. For now, you won't notice much apart from slightly different commands. However this allows me to add support for other NPC systems! Currently, it's planned to be able to use MythicMobs, or any entity/mob, as NPCs (e.g. as quest givers)
• [^] Huge internal changes, allowing me to add even cooler features in the future
• [!] Fixed a lot of bugs in the process which I can't count. Because of the big list of internal changes, this might introduce many new bugs, though. The next updates will thus be focused on fixing these bugs, if there are any.
