talks/2011: copy in the lexical scanning talk from its old location

It resides in my personal repository, but that
will go away and anyway it belongs here, a place that did not
exist when the talk was given.

The only edits are formatting for the present format, an added
line about Go 1 allowing goroutines in init, and a file rename
to avoid a git gofmt precommit.
