* fix: List details of feeds for OPML exportation
The details are necessary to export the XPath information, the CSS full
content path and read actions filters.
* Update LibOpml to 0.4.0
* Refactor OPML importation to be more robust
First, it fixes two regressions introduced by the update of lib_opml:
- title attribute is used when text attribute is missing;
- the OPML category attribute is used as a fallback for feeds categories.
In a related way, if also fixes a problem when a feed had both a parent
category outline and a category attribute. Before, it only considered the
attribute as its category, but now it considers the parent outline.
Then, it counts category limit correctly by not increasing
`$nb_categories` if the category already exists.
