• VSCode Version: 1.0.0
• OS Version: Fedora 23 x86_64

Steps to Reproduce:

1. Install VSCode
2. Install Puppet Extension
3. Open puppet manifest (.pp file)
4. VSCode detects it as a Ruby file type

package.json snippet of offending extension:

            "id": "ruby",
            "extensions": [ ".rb", ".rbx", ".rjs", ".gemspec", ".pp", ".rake" ],

The included Ruby language extension has the puppet extension (.pp) in its extensions list and overrides any installed Puppet extension causing Puppet manifest files to always be detected as Ruby files unless a manual override is put into the User Configuration.
