godoc: inject treeview content only when needed

- This shaves off 12.8KB (unzipped) / 3.8KB (zipped)
downloadable data and around 6ms of javascript parse time
when the files are not injected.

- Also, conditionally rendering the callgraph html only when
callgraph is actually present.

- Removed the "text/javascript" attribute as it is the default
value now.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
