[MultiTag] Store an array of refs to currently selected tag divs

[conor-cafferkey-sociomantic]

Currently

In several places in the code above we loop over refs.multiTagWrapper.childNodes to get the currently selected tags.

Problem

This is slightly messy because since #122 the multiTagWrapper div also contains the searchbox (refs.search), meaning we always need to exclude the last child.

Wanted

It might be a better idea to maintain an array of references to the currently selected tag divs: flounder.refs.tags. This would be similar to the array of option divs in flounder.refs.data or sections divs in flounder.refs.sections.

• keeping an array of option divs hidden by search filter would be useful for https://github.com/sociomantic-tsunami/flounder/issues/165
• likewise, an array of selected <option>’s and corresponding divs would be useful for https://github.com/sociomantic-tsunami/flounder/issues/162
