Support for starting and stopping multiple servers in the same PS session

[TylerLeonhardt]

We should be able to do:

$app1 = Start-Polaris -Port 8080

New-Polaris

$app2 = Start-Polaris -Port 8081

Stop-Polaris $app2
Stop-Polaris $app1

Where New-Polaris creates a new Polaris object and puts it in the existing global $Polaris variable.

This also means that all New-*Route cmdlets should allow a -ServerContext param where you can pass in the server you want to add a route to.

Example:

$app = Start-Polaris -Port 8080

$sb = { $response.Send("atlas") }
New-GetRoute /hello $sb -ServerContext $app

This is actually almost done. Work remaining is:

• create the New-Polaris cmdlet that creates a new Polaris object and stores it in $global:Polaris
• add -ServerContext to New-*Route

This is possible now.
