Allow adding context to Search Results

Consider the following typical code snippet:

connect(m_timer, &QTimer::timeout(),
        this, &Class::slotTimeout());

When doing "Find Usages" on m_timer, I get the following search result:

530     connect(m_timer, &QTimer::timeout(),

If I want to see where the signal is connected to, I need double click the search result to open an editor at that position.

It would be very convenient to optionally display a number of context lines before/after each search result (maybe like the DiffEditor allows for chunks).

Maybe it would already be enough to have this extra information as tooltip.
