Documentation for build-depends on hover

Documentation for build-depends on hover.

If you hover over the field under build-depends it will give Documentation with a hackage link to a package.

Implementation details

This is a naive solution for this problem, hovered text is filtered using a regex and compared to found dependencies from PackageDescription. If it was found, then the Documentation message is added, otherwise left as is.

This approach assumes, that if a package is mentioned in a cabal file, there should be a link with the same name. In this implementation there are no spelling checks.
