Categories, Total Members, Upcoming Events, RSVP event btn

[Alek-S]

• Removed MeetupLink and converted to MeetupCard and placed in components folder
• Added styling to Learn More anchor
• Added color-coded categories to each meetup
• Added Vue, Elm and Flutter meetup groups
• Added Meetup API call to grab current total member count
• Added proptype package for validation
• Added fetch-jsonp to make jsonp fetch request to bypass CORS

Important Note

• The API call to meetup api is rate limited by meetup. If rate limit is hit, total members section will be hidden since nothing to show as quick work-around

• With the new categories, thinking of adding button area at the top to filter by type of meetup (all, front, back, etc)

PR ready for review.

Additions:

• Utilize Bootstrap UI components more (badge, pill, button, container etc)
• Show Upcoming group events from meetup api, with event rsvp btn (example image below)
