Add support for user-defined labels

[Alkarex]

Hello,
In the GReader API (implemented by FreshRSS), there is the concept of user labels (also called tags sometimes), which would be nice to support in CapyReader. It is not the same concept than article tags, which are defined by the original Web site.

A user can add labels to articles to classify them or to re-share them.
Labels can also be added automatically by FreshRSS on incoming articles.

An article may appear in a feed as well as in multiple labels (and potentially also in the "read later" / favourite list).

Here is a screenshot from News+ as an illustration:

Do not hesitate to ask if if you need any additional documentation / examples.

This is the main feature missing from the list of apps compatible with FreshRSS before we can recommend an app.
