Subject: [PATCH] [xExtension-YouTube] Silence DOM warnings when showing the
 feed content

When "Display the feeds content" is enabled, getHtml() parses the entry
content with DOMDocument::loadHTML() to extract the enclosure title,
thumbnail and description. FreshRSS renders enclosures with HTML5 tags
such as <figure>, <figcaption> and <video>, which the libxml HTML 4
parser does not know, so every YouTube entry emitted warnings like:

    Warning: DOMDocument::loadHTML(): Tag figure invalid in Entity

These warnings were printed in the middle of the article stream and
filled the logs.

Pass LIBXML_NONET | LIBXML_NOERROR | LIBXML_NOWARNING to loadHTML(),
the same flags FreshRSS core and this extension's icon downloader
already use when parsing third-party HTML. The parser still recovers
the same tree, so the generated content is unchanged.

Bump the extension version to 1.3.2.

Fixes #222
