Issue Description

Not sure if this is considered a bug or not, but I noticed that when you use scope modifiers ($script: $global:, etc.) or the $env: prefix, these variables do not evaluate when hovered over like normal variables. They do display if paste them into Watches however. Is this something that is already a known issue or has plans to be addressed.

Also, I have additional feedback I would like to provide, is there a process to submit enhancement ideas to be evaluated?

Reproduce el problema en VS Code 1.8.0 con la extensión de PowerShell 0.7.2 usando la versión de PowerShell proporcionada y compare la evaluación al pasar el cursor con Watches para los modificadores de ámbito y el prefijo $env:. Se considera terminado cuando estas variables se evalúen correctamente en la información sobre herramientas del cursor y se conserve el comportamiento existente de Watch.
