Adds more menu items to the "More" drop-down list on all Steam profile pages. These are currently:

• SteamRep Page
• Rep.tf page
• Backpack.tf page
• TF2 Outpost page
• Bazaar.tf page
• Show SteamIDs
• Open Profile in Steam Client

(more will be added in future versions)

Uses peterolson's BigInteger.js for handling SteamID64s. And of course jQuery™.

Ideas are welcome on the issues page.
