A user can search for tasks

[fynnfeldpausch]

As a user, I want to search all tasks so that I can find relevant tasks quickly.

Acceptance criteria

• the user can search tasks via a search input
• the search is performed instantaneously ("search as you type")

Optional acceptance criteria

• the search can be reset with a single click
• the user can deep-link to a search result (e.g. call URL?q=search and find the search pre-filled)
• the user can use search operators (e.g. AND, OR, ...)
