Social Media icon colors and classes are confusing

[neerajt]

The classes for the colors are misleading (e.g., Facebook is used for other icons for the background color) and don't match. If at all possible, the color for Meetup should be red to match meetup's color scheme.

Proposed fix:

• create new classes with the color names to avoid confusion
• shuffle icons to make meetup's icon red
