[Plugins] Allow to manipulate the feed list

[sjehuda]

I have several ideas for Liferea, which are not yet possivle to realize with pugins, yet.

Those ideas are not only for Liferea, but also for any News Reader and even for Browsers software.

In order to realize those ideas, I would need the plugin system to make it possible to retrieve and modify the feed list.

Synchronize feeds with XMPP accounts

• Plugin: Synchronize via XMPP (no server needed) #1343
• Plugin: Sharing news and feeds with other friends who use Liferea #1344

Liferea to read XMPP subscriptions

• Plugin: Read XMPP PubSub node items as Atom Syndication feed #1356

Liferea as a publishing software

• Plugin: Publish news and feeds to Libervia and Movim #1347

400920d is a refactoring that make the "node" object accessible via GIR. Note that this is not yet enough (several other objects are also needed), but "node" was the largest change needed and is done.

Thank you, dear Lars. I will experiment with next version of Liferea or with gti version. https://aur.archlinux.org/packages/liferea-git

The necessary refactoring is still ongoing. Today I got time to refactor the "UpdateJob" stuff 39ee8ac

open TODOs

• "UpdateRequest" as GObject
• "UpdateResult" as GObject
• new class "UpdateJob" as GObject
• isolated code for update_job_queue
• "Node" as GObject
• "NodeSource" as GObject
• "Subscription" as GObject (maybe it could work without...)
• adding methods to "NodeSourceActivatable" interface
• example node source plugin
