Hamish Friedlander a5f00ae2c3 FIX Not checking stage in SiteTree#canView
SiteTree versions that arent the live version shouldnt be accessed by
regular users, but the logic to check that was split off into canViewStage,
which wasnt checked by code that isnt specifically SiteTree aware
(like RestfulServer)

/**
* The most common kind of controller; effectively a controller linked to a {@link DataObject}.
*
* ContentControllers are most useful in the content-focused areas of a site. This is generally
* the bulk of a site; however, they may be less appropriate in, for example, the user management
* section of an application.
*
* On its own, content controller does very little. Its constructor is passed a {@link DataObject}
* which is stored in $this->dataRecord. Any unrecognised method calls, for example, Title()
* and Content(), will be passed along to the data record,
*
* Subclasses of ContentController are generally instantiated by ModelAsController; this will create
* a controller based on the URLSegment action variable, by looking in the SiteTree table.
*
* @todo Can this be used for anything other than SiteTree controllers?
*
* @package cms
* @subpackage control
