call getObject() once explicitly to reduce number of calls.

this code was working just by chance because active_knowledge_pad is a brain, not an ERP5 object.

-Titlecase terms, uppercase abbreviations, avoid jargons, add titles to empty title forms....

First select pads for current user, then if it's anonymous user and it's preferred so return public knowledge pads for context. This change allows logged in users to have their own customized pads independently from value of a web site preference : "Force Anonymous Gadget " and still we can show or hide public pads for context for anonymous.

In case still we want to show default pads for logged in users we can use preferences which can contain knowledge pads templates. The templates can itself be customized which allows a KM or ERP5 UI site to show a set of default pads for any context which with a single click can be adjusted by user to his needs.

Refactor code to remove code duplicated related to get real context. Also, the language is removed if exists and the context is a Web Section or Web Site

also fix a bug in getting real context logic where url is like web_site/lang/referefnce.

Do use catalog when switching between different tabs to avoid having to deal with objectValues / contentValues API. Avoid use cases when a Pad may contains many Boxes.

Add a new preference to allow show directly links to remote content in RSS reader (keep default behaviour as it is).

In some very specific cases it's usefull to allow a gadget instance define its own view form (i.e. when rendering remote content in some case we want it done it synchronously for SEO).

In some cases a Box can override Gadget default way of rendering (usefull in cases when we care for SEO for anonymous users).
Make RSS feed more visible.

Introduced by mistake in 7ff48df4

There is no control where context would be used.

Make all gadgets in a public state by default as the gadgets itself can be used in building Web sites (KM) for anonymous users.
It is safe to make them available to public as they just contain the "way" UI should be constructed (not the data that will build the UI itself).
