[Search Results]: add "Copy with line numbers" option

[PetbkA]

Lines from search results are copied without line numbers. It would be nice to have such option (may be with customizable hotkey, e.g. Ctrl + Shift + C).

Preferrable output is like in Notepad++: Line <LineNum>:<Space><Line>

Don't know if it'll be useful to also copy file path

Great idea! I've added it to a backlog.
