Improve public link share mail address input field

[pmaier1]

The current mail address input field for public link shares is too small and does not work well when entering more than one address. It would be great to have it similar to the following screenshot:

Requirements

• input field is adaptive (auto-scale)
• mail addresses become "fixed" by hitting space as in the screenshot
• mail addresses can be "unfixed"/deleted letter-wise with backspace and have a "x" to delete them at once

A mockup would be great!

Nope, this was not done so far. @pmaier1 are we sure this is necessary? Can we move this to the backlog? Other things seem more urgent.

Yes, it's important. This is a p1 item in the milestone for the next release. Also it's a prereq for #29938. Let's speak if there are concerns.

let's use select2 which is already included with ownCloud core, see http://select2.github.io/select2/ and search for "Tagging Support" as agreed when discussing with @felixheidecke

also needs to support autocomplete, see #30645 (comment)
