Implement the query suggestion logic

[donhardman]

We should design and display query suggestions in the same way Google does, and use the latest code from Buddy to accomplish this.

The user input should bounce with a slight delay, and with almost every keystroke, we should render and display a popup placed under the search input.

The task consists of 3 subtasks:

• [x] Implement the design and client logic
• [x] Integrate the required changes to the Manticore PHP client
• [x] Integrate the backend endpoint in the demo project that will handle query suggestions

[donhardman]

The integration is complete. If everything works well from the client's perspective, further improvements will focus on the Fuzzy-related tasks in Buddy.
