Title: [Bug 651226] Add Windows versions to showfor.

Add 'winxp', 'win7', and 'win8' showfor tags, and hide the 'win' showfor tag from user selection. Document editors can still select 'win'.

Additionally, added some logic to make 'win' tagged content show up if any of the versioned tags are selected, and logic to make any versioned tag show up if 'win' is selected (such as via a saved url).

This has the net effect of allowing us to start giving different content for different versions of windows without breaking backwards compatibility.
