Provide search store

[Blagoja95]

Implement search for search component and enable its usage;

Story:

1. User enter search term
2. All tasks, teams and users are found by entered search term (one batch call)
3. Return arrays of search results
4. Iterate through search results and displayed nicely packed result.
5. When user press specific result (user press task) user is redirected to detailed page about that result

Search results are cashed and always displayed to a user until he:

1. press clear button inside search bar
2. enter new search term
3. exit application (not sure, see caching option below)

• effort for highlighting term inside every result
• clear button
• caching on backend
