If the option is not valid for MySB.com, then we should remove it from the menu

Design plan, when switching servers from A to B, got build up the list of items unique to A and remove those menu items

Also, this fix should look at player to player changes and SC to SC changes to menus as well.

Moving to the product SqueezePlay because this bug appears to apply to any
player based on that application code.  Feel free to move it back if it's
specific to the single original product.

Reset priority before triage.

This actually only applies to server changes not player changes. When palayers 
change, all server-feed menus are detroyed (and all server screensavers are 
unregistered)

A part of autoswitch is to offer options that one server has that the other doesn't, but that logic only makes sense for service offerings not server-fed device settings.

xfade and other settings are all also available via SN, so the "setting on one but not the other server" part isn't valid. I no longer can reproduce the stated issue, so I'm marking works for me.
