Implementation: OutdatedSubState (OutdatedState)

[lemz1]

ADDITIONS

This pr adds the implementation for the OutdatedSubState. (Well now its OutdatedState)
It checks the html of the itch.io page and retrieves the versions.

It uses HtmlParser to parse the HTML.

NOTE

I wanted to use the itch.io API but for the love of it, I couldn't find a way to retrieve a list of the uploaded files. If anyone knows how to retrieve them, then please share, because i don't like that we parse HTML to retrieve the versions. It's probably slow and unsafe.

PREVIEW

I do wonder if changing it to be an alert would be better. I just went with the old implementation of the OutdatedSubState

I think for this we would want to update it to use the itch.io api, so then stuff like mac version will check if theres a mac version update, windows can check windows, linux can check linux, etc.

havent looked too deep into that api yet, but we do want this screen back in some form !

sounds good to me. Will need to look into the itch.io api and see how i can retrieve the versions
