Title: Do not register Zotero as the Start Menu Internet Link.

Windows XP and Windows Vista have a special Start Menu Internet Link in the start menu. This menu item can be customized by registering an application in the registry under Software\Clients\StartMenuInternet. This registration is ignored in Windows 7 and Windows 8.

Zotero's installer was partially filling in this information, and the uninstaller was failing to remove it.

The uninstaller was also deleting a key under Software\RegisteredApplications. This key is used for the Windows "Default Programs" feature, which Zotero is not using. The installer was not writing values to this key.
