Automate Resource submission and approval #279

We should make an official web form for submitting resource submissions for approval.

https://monogame.net/resources/

• Asks for all the relevant info.
• Allow you to upload the images.
• Preview what the resource submission looks like.

Once submitted it should send an email to an @monogame.net email with a link previewing the submission and a click to approve or deny it.

This should help us add to the resources much quicker and with more quality.
