Add photographs to the sign in page

[anthonycrumley]

See discussion in #21 concerning photographs.

Understanding:

• Participant comes to sign in table
• Person signs in using interface
• Takes picture/picture is logged in their sign in file
• Volunteers/Connectors are able to use picture to remember what participant looks like during Network Night and when following up with participant

Benefits

• Makes it easier to identify people in the interface. (Or does it? They have name tags.)
• Puts a picture with matches and nodes automatically for the Hot List

Concerns

• Might be off-putting to some people.
• Privacy issues.
• Camera API for the browser their tablet uses.
• This could slow sign in down significantly--explaining the picture taking process, participants asking why their picture is taken, etc.
• Unless privacy was checked off during sign in, this becomes a huge concern. This does make me think that we need to add a privacy question on the sign in....something to this effect: "We take pictures to capture the story unfolding during Network Night. Do you give us permission to take photos of you/around you?"
