set HTML meta keywords as tags and meta description as defaults

[webmarka]

Agree it would be nice if the meta description was loaded!

Same for meta keywords (and eventually other kind of meta/header/semantic infos).

Even if it's true meta keywords could be filled with scrap from the page, personally I generally do not bookmark those sites!!

I would prefer a higher maximum like 20, but it may be taking too much space in the tags field ?

Those params could be in the app options (auto fetch descriptions, tags) or in personal/admin settings if we want to keep app options panel clean.

Meta tags were used by spammers or wannabe-SEOs a lot, but reasonable if it implies a limit of allowed terms (5, 7, 10, other?).
