Add a debug mode for project mode and other languages

Back in 2018, Repl Talk beta was first announced in [Amjad's post](https://repl.it/talk/announcements/repl-talk/5053). The post mentioned that you would be able to spend cycles for more cpu/memory/storage. The post also said that "We'll announce this officially soon." This has not happened yet, and it's been over a year since they said this would happen "soon". This would be really useful for big projects so they don't crash as often, or just if you want to execute things faster. Also, preferably it wouldn't remove the cycles from your count and instead there would be a different view for viewing your available cycles. Please upvote this post if you also think this would be great.

I'm taking a python class (real class in school) often I cannot connect to server and my rep lt will not load, save data!!!!!

This is just copy and pasted from my ask post. Shouldn't repl.it add a feature were you can chat with others? Like a chat bar on the side, kinda like the chat in multiplayer repls, but instead you can chat in anywhere but the code. I don't think this really makes sense. My bad if it doesn't.

I think it'd be a fun idea to have a live chat system for helpers. I've seen the "chat with us" icon on other sites, which creates a ticket and connects with a listener. It would be really cool if helpers had the ability to chat in real time with people in need. Also, maybe a ticketing system too so we can make sure that every question gets answered (or that every person who spammes gets reported).

Make the repl.it feedback page support markdown, so you can make posts like this: `code();` *italic* **bold** _italic_ ~~strikethrough~~ - List - List ``` Multi line code() ``` And so on like in the repl.it talk page. EDIT: The single line code formatting already works

I like how repl.it support GUI running, but it is painfully slow with very low fps that makes it unreliable

I hope you're having a good day

I love the Love2D Integration on repl, but I'm becoming increasingly aware of how painfully low framerate the preview is when you run your code. The gif attached is not choppy due to compression - this is literally how it looks.

update node to v12
