Add basic OwnCloud News support

[kodchi]

I'd appreciate any reviews. I know the code can be made better, but I think it's a good start.

@kodchi Awesome work! My only problem is I cannot test it, as I haven't setup owncloud for me yet. I hope I find time soon.

[lwindolf]

Ah I just saw there are many free plans for Owncloud at different hosters. That makes it easy for testing. I'll use one for testing.

If it works well I think it might be worth propagating to use Liferea with OwnCloud as a good alternative for vserver / root-server based self-hosting.

[kodchi]

Cool, I'm keen to polish the code to make it working if you see any problems.

[lwindolf]

@kodchi Despite several tries I failed to set up an own working owncloud instance (version 9 mostly) or use a free provider. The free providers all have no news support and in my own test setup (Ubuntu 16.04 based) I guess there could be an API mismatch.

Maybe you have a test account for me?

[kodchi]

Unfortunately, my owncloud instance is also local. I don't think the API has changed recently. Are you having a problem with owncloud itself or the news app?

[jajaX]

Hi,

I test liferea and I have got owncloud news too. I can test if you want.

Tell me how I do please ?

@jajaX Check out the "command line instructions" below for checkout of this PR. Then do normal compilation and installation and you should see a new "Source" provider for OwnCloud.

I'll fix up the merge conflict soon, but I'd also like to help test the change. Would it help if I uploaded a Virtualbox image with a pre-installed ownCloud News app help? Let me know. Thanks.

[lwindolf]

@kodchi Sorry for taking so long to reply: yes that would help!

[marathone]

So I'm a little confused - Is Opencloud/Nextcloud supported in Liferea or not?

[Leiaz]

@marathone No, it is currently not supported.

[kodchi]

I promised that I'd upload a Virtualbox image, but unfortunately I'm not using owncloud these days. Someone else, please feel free to take over the pull request.

An update on this: I'm currently working on a NextCloud News support plugin. This should also work with OwnCloud News. While working on this @kodchi code here helps a lot!

Note: the "News" maintainer moved on to NextCloud and it is not possible to install "News" anymore from the OwnCloud extension market place. So future focus of users will probably by NextCloud (with Owncloud legacy users).
