Dolphin Services: Add search box

Summary:
You can now filter the list of installed services.
This is especially useful if you install additional service menus
from the kde store, because one instalaton can add a lot of services.
For instance the ReImage plugin.

Test Plan:
Compiles, search for a service menu.
Only services matching the query will show up.
