'auto-resizing' images broke responsiveness

The auto-resizing images 'feature' by the other contributer broke
the design and the responsiveness of the website. Removed the two
rules. Using square images is essential.
Fixing tradzik.jpg to be a square image for compatibility
Adding icon font files and CSS rules
Adding font files + HTML
Added social overlays to each person & updated fonts

Instructions for adding can be found in a comment in the first
person HTML. Added correct links and Github accounts for mentors,
website and facebook for a student, and github and email for my
own self. Updated fonts for more icons.
Adding menu with link to blog and a test link

Menu has FOSSASIA logo and links to the blog. Minor changes
elsewhere in the stylesheet to accommodate shifts due to
menu's code.
Merge latest changes from upstream

Added student's name a links to the new person design.
Changing person--mentor to person--student for students

Bringing in Namanyay's nice work.
Changed christoper.jpg to chris.jpg

Chris fixed this mistake in an earlier commit. But I probably messed
something up during the recent merge. Anyway everything is fixed and
working now.
