godoc: better distinguish links and link state

There were two issues with links in godoc:

1) They were only distinguished from ordinary text only by color,
affecting those with color-vision deficiencies.

2) The same blue used for links is used by non-links,
affecting everybody.

This change adds a an underline to all links.

Usually, it is safe to skip underlining in locations where it clear
that the only contents are navigational links, such as #pkg-index.
However, (2) prevented this.

To work around this I used some less well supported CSS techniques:
http://caniuse.com/#feat=text-decoration

Less capable browsers, which are unlikely to be used by developers, may
have a less than optimal experience, unfortunately. In more capable
browsers, including those without full support, the experience is quite
pleasant and the additional underlying does not interfere with the godoc
aesthetic.

For golang/go#22171

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

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.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
