Add support for dotnet help <verb>

Browse source 
This commit adds supports for getting more detailed help by using the
`dotnet help <verb>` syntax (e.g. `dotnet help build`). This change
opens up the URL that is specified for each verb in the default browser
on the user's machine, so internet access is required.
