Stop pointlessly passing the WebEvent argument

[Badgerati]

In Pode there is the WebEvent, which contains all of the Request, Response, Header, Cookie, etc info for a current web request. This WebEvent is then typically supplied to Routes, Middleware, etc as a first default parameter:

Add-PodeRoute -Method Get -Path '/' -ScriptBlock {
    param($e)
    Write-PodeJsonResponse -Value @{ Message = "Hello, $($e.Query['name'])" }
}

However, it's actually possible to just use $WebEvent.Query['name']!

Add-PodeRoute -Method Get -Path '/' -ScriptBlock {
    Write-PodeJsonResponse -Value @{ Message = "Hello, $($WebEvent.Query['name'])" }
}

The above works exactly the same, and works in Routes, Middleware, and Authentication (Method, Validator, and Post-Validator - each of which don't have it supplied at the moment!)

The docs will need a big clean-up, but it should make routes cleaner not having to constantly do param($e).
