Ability to change the colors outputed by Write-* for -Warning, -Debug, -Error and -Verbose

Basically this functionality should work as in Windows PowerShell, so this code should produce results WPS behaviour:

$Host.UI.RawUI.BackgroundColor = ($bckgrnd = 'DarkRed')
$Host.UI.RawUI.ForegroundColor = 'Cyan'
$Host.PrivateData.ErrorForegroundColor = 'Red'
$Host.PrivateData.ErrorBackgroundColor = $bckgrnd
$Host.PrivateData.WarningForegroundColor = 'Magenta'
$Host.PrivateData.WarningBackgroundColor = $bckgrnd
$Host.PrivateData.DebugForegroundColor = 'Yellow'
$Host.PrivateData.DebugBackgroundColor = $bckgrnd
$Host.PrivateData.VerboseForegroundColor = 'Green'
$Host.PrivateData.VerboseBackgroundColor = $bckgrnd
$Host.PrivateData.ProgressForegroundColor = 'Cyan'
$Host.PrivateData.ProgressBackgroundColor = $bckgrnd
Write-Host    "                    Write-Host                  "
Write-Verbose "                    Write-Verbose               " -Verbose
Write-Error   "                    Write-Error                 "
Write-Warning "                    Write-Warning                 "

However since we are running in a HTML styled scenario this can even be improved and we can retrofit the colors for already typed regular Write-Host text.
