Update people's affiliations and other general links

[bearecinos]

TODO list:

• Update on people's affiliations. Is it worth to ask around if people want a specific link to be added to their names? etc?
• Publications (@fmaussion said it will do)
• Maybe add a link to the new cryosphere tools repo in github?
