Mention plugin development

[snewcomer]

I started a sketch of a mention plugin. Perhaps prematurely but we can use this as a place to scope out high level features.

API

• trigger with default to @
• children
• onSelect
• onSearch with default to fuzzy search

UI

• Do we have anything to reuse or do we need to create a ListItem component?
• Is it possible to yield out the child render to the call site? This @ mention component could be used for an arbitrary object - users or other types of objects a user wants to query / insert into the page.

ember as an example

<ListItem>
  <:child as |child|>
    <Avatar>
    {{child.name}}
  </:child>
</ListItem>

Other

• Keyboard navigation
• Keyboard events like Esc and Enter

Feel free to add to this scope or discuss what constraints/features could be added
