widget deprecated hooks

[GoogleCodeExporter]

widget registry needs to know if a widget is deprecated. 

a deprecated widget should point to a new widget.

should the deprication be on the side of the widget that is depricated or the 
new one?

I think it should be part of the widget xml

<depricates>base_rbind, base_rcbind</depricates>

Some rules would need to be in place so that malicious packages don't depricate 
useful things...

perhaps each package should be signed with a key (gpg key) and to include a 
package on red-r.org the package must also contain the key of the person who 
made the depricated widget

in fact perhaps all packages should be signed with a gpg key which we can use 
to track users and collaborative packages
