Install with standard go tools

[DanielHeath]

Go has a built-in method to install packages like this one: go get github.com/jgrahamc/webwatch.

Unfortunately, it doesn't work with this package, because the code is stored under src/webwatch in the repository.

A user could type go get github.com/jgrahamc/webwatch/src/webwatch to get it to work, but it's kind of awkward.
