Update my name

[gsnedders]

There's a few files in tests/ that refer to me as Geoffrey; these should be updated to Sam.

Given they're in tests, I don't know if there's any expectations anywhere I need to update, and I don't have the time to figure out how to run them.

./tests/specifications/ED-respec-test-20100224.html
611:        Many thanks to Marcos Cáceres for moral support, and to Bert Bos and Geoffrey Sneddon for their

./tests/specifications/snapshot-as-html_source.html
122:        Many thanks to Marcos Cáceres for moral support, and to Bert Bos and Geoffrey Sneddon for their

No problem. Will get then fixed for ya. I don’t think anything touches those files and pretty sure nothing checks the names.
