Accept share of multiple URLs

**Is your feature request related to a problem? Please describe.**

I'm using wallabag Android client v2.5.3 (233).

I have a giant pile of tabs open on my phone that I would like to move into wallabag. As far as I can tell, the only way to do this is one at a time: select each tab, tap the menu, tap share, tap the wallabag icon, and then tap the little square with the arrow on the pop-up for editing the title and tags. Since I have nearly 100 tabs open, this is incredibly tedious.

**Describe the solution you'd like**

I would like this to work: go into the tab overview screen, select all the tabs I want to move to wallabag, share -> wallabag, *done*. In this mode it should not bother prompting to edit the title or the tags, it should just send all the URLs straight to the server. Assume the user will sort out the labeling later.

If you do this now, what happens is it brings up the pop-up for the first tab and ignores the rest of the URLs, which is more than a little surprising.
