Frontend: Search Bar

[cw00dw0rd]

We will have queries that rely on natural language search and would need a more traditional search input. There is currently no placeholder for this component and it would need to be added.

This will be required for AQL #11

Idea: The search could be initiated with a button on the current search bar, this button should be the ArangoSearch magnifying glass icon.
