Superseed the PR #1345

This feature allows to set common options to all needs in a list defined by list2need directive.

Comparing to the PR #1345, I implemented a new list-options option with the ability to nest all options that will be common (I removed the hide specific option as it can easily be added in this new list-options

I left a regex matching on the list-options value allowing to aggregate options that could be defined in one list item through the meta-data feature.

Thanks @christopheseyler, this is definitely better, but bear with me a little on this as I want to have a bit more of a thought on it

Hi, Do not worry, take your time.

Just note that I still kept the :tags: option al list2need level, even if it could also be included in the :list-options: as well. I think that the tags is so "common" for the needs (used for filter) that having its own "option" is a better choice than buried it in the list-options. (I hope you understand what i mean ;) )
