Preloading support in browser

	   Apps like the QSB can request the browser to preload a
	   web page.
           - preloaded pages are not added to the browser history
	     if they'r not seen by the user
	   - when a request is received, a new tab is created for the
	     preloaded page, but not added to the tab list
 	   - upon receiving the view intent for the preloaded page
             the tab is added to the tab list, and shown
	   - if several pages are preloaded consecutively in the same tab,
             the back stack is cleared before it is displayed
           - preloaded pages use the main browser cookie jar, so pages that
             have never been viewed by the user can drop cookies
