Link to hexdocs.pm on function hover

[ascandone]

It might be useful to have a link that brings you to hexdocs.pm documentation, like in elixir:

A possible implementation could show the link only for values that:

• are imported from external dependencies
• that are hosted on hex

@lpil I managed to implement the "View on hexdocs" functionality only for hex dependencies. Is it still possible for the link to go 404 if the dependency is published on hexdocs.pm ?

It is possible, but it's pretend it's not :)
