Custom 404 page support

[TheDude53]

There should be custom 404 page support so it doesn't just say "entry not found". It could be useful if people wanted a custom page to go with the rest of their work.

Good idea. Maybe if you have a 404.html in the root directory it would just show that, for example?

[TheDude53]

Yes, that would work. It could just default to the "entry not found" if a 404.html page wasn't found too.

404.html is probably the best idea for a quick implementation, as it is compatible with GitHub pages.
Allowing the user to manually select the file should also work, but risks overcomplicating what is supposed to be a simple, ready to run, server.

I can not open the server it's just showing 404

@kzahel I am thinking about implementing this but I need some help. How would I upload the file to the extension to save it as a 404.html? Would I need to store it using local variables or however google chrome apps do it. Also, any ideas on the UI. Reading the 404.html would be easy but saving it is the hard part.

@kzahel @TheDude53 I have built this - Because Kyle doesnt seem to be active on github anymore you can download my archive.zip and load it through chrome://extensions
