Update the Project Creation form to be consistent with new requirements (6th November 2021)

[AVS1508]

This PR is intended to fix #260 as well as fix #261.

Requirements

• Make video links mandatory in the Project Creation page
• Change functionality of wall outlet field in project creation form to verify whether the user is participating virtually

Changelog

• Updated the Project model to validate the presence and format of YouTube link [validates the format of the youtube_link (allowed to be blank so that it doesn't show 2 errors if absent as we're already validating its presence above) if it is indeed present because it needs to start with https://]
• Updated the Project Creation view to be consistent with model changes and new requirements
• Updated the Project creation form view to have the checkbox for virtual participants [Note that the question now asks for confirmation of being a virtual participant and not the wall outlet requirement so while this may not be the best practice for long term development, I am leaving the form field as supplying the :power symbol in the interest of not wrangling with model changes and creating updated migrations in the middle of the event.]
