Breaking: Rename global properties

[caendesilva]

This will hopefully be the last breaking change. The old accessors are present but deprecated and will be removed before v1.0-proper. I think the RC break is justified here as since the properties are not documented I don't think many people use it so the impact is low, and the naming issue is quite severe. These are legacy properties introduced before route keys were a thing.

• The global $currentRoute variable will be renamed to $route as "current" is implied
• The global $currentRoute variable will be renamed to $routeKey as "current" is implied, and it's not a page.

For this, the location of the actual shared variables (in the ViewData) class are also deprecated, and updated for the renames. Most of these changes should be easy to upgrade with search+replace in project files.
