event registrations

[nagarajpandith]

• a feature which adds a register button to events on /events page
• add a new boolean to 'Event' model (by default false) to toggle the event registration availability on or off. relate user and event model (one to many)
• this must add a checkbox to all events on /admin/event to toggle availability
• register button shows a registration modal which takes inputs like name, usn, branch, year, email, phone number and other extra things (if any)
• a lot of things here can be prefilled in the modal (usn is user.email.split("@")[0], email is user.email, year & branch can be extracted from email in the same way)
• if isMember is false, "submit" button on modal must redirect to razorpay gateway, amount set on admin panel
• check if user is already registered, don't show the modal again

[nagarajpandith]

• ability to admin to edit form fields (edit = enable or disable particular fields for particular events), to decide whether few fields should be shown for a particular event
• feature to export registered members list/info as excel sheet
• showcase the most recently added event on home page if it's registrations are open (isAvailable=true)
