Allow "current user" in Calculated Properties

[atrosper]

When creating a calculated property, I wish there was a way to pull in and compare against the Current User's properties.  For example, when you are using the Filters in some areas of the site, you can use the dynamic "Me" option, shown below.

I was hoping to create a custom calculated property that compared a couple of different properties against the current user, and then returned a true or false. 

Something like this:

if([Owner] == current_user] OR [CoOwner] == current_user){
   return true;
}else{
   return false;
}

 Or maybe it would need to be one of these:

current_user.id
active_user
__HS__ID
[DyanmicProperties.Me.ID]

Hope this helps!
