A+C: manual updates

Add Colin Cross (Google CLA)
Add Quentin Perez (Individual CLA)
Add Andy Balholm (Individual CLA)
Add Dirk Gadsden (Individual CLA)
Add Derek Che (Yahoo CLA)

And:

Add CL Sung (Individual CLA), but where gerrit is using personal email
address with CLA signed, but the git commit itself is using an
unverified htc.com address. The commit is:
    https://github.com/golang/oauth2/commit/099e4f0
For github user https://github.com/clsung which says "Self-Employed"
and "clsung@gmail.com". Perhaps the self-employed part is new
since Sep 10, 2014.
