Show the line text in search results instead of line no & col

This is a proposal.

Currently search & replace plugin shows "Line: xx, Column: xx" which IMO is not very useful. With this change the actual line is displayed with the matching text highlighted in the same color as that of the editor search-highlight color.

This makes the search plugin very useful for cases where you want to see some very similar lines or see uses of something. An example use case which I often come across is that suppose you have a big log file and you are looking for only WARNs. You just type WARN and in search results you see all the lines that contain WARN. Now you can quickly analyze them.

Additionally the results can also be displayed in mono font but I haven't made that change. Screenshot:

Also, we can use the colors from the current color scheme to set the "selected item" color or even background color to give a more seamless feel. Something like:
