Description

Create a new property that allows you to set both the visible and includeInLayout properties at the same time.

Steps to reproduce:
1.Add a component to the stage
2.Set visibleInLayout to false to hide and exclude from layout
3.Set visibleInLayout to true to show and include in layout

Actual Results:
not created yet

Expected Results:
when you set the property to true or false:
2.Set visibleInLayout to false to hide and exclude from layout
3.Set visibleInLayout to true to show and include in layout

Workaround (if any):
Set visible to false and set includeInLayout to false.

Notes:
In nearly every project I've worked on I see two lines of code for hiding and then excluding from the layout. 

This new property would combine visible and layout into one line using one property.

// this code
mainContainer.visible=false;
mainContainer.includeInLayout=false;

// becomes
mainContainer.visibleInLayout=false;

Without it you get code all throughout a project that looks like this:

mainContainer.visible=false;
mainContainer.includeInLayout=false;
loadingProgress.visible=true;
loadingProgress.includeInLayout=true;

private function onWallLoadingStop(event:NavigationEvents):void {
 loadingwallprogress.visible=false;
 loadingwallprogress.includeInLayout=false;

 if (event.str == "ActivityStream") {
  mainWallContainer.visible=false
  mainWallContainer.includeInLayout=false;
 }
 else {
  mainWallContainer.visible=true;   mainWallContainer.includeInLayout=true;
 }
}
