Add line numbers

Add line numbers to search results. Also clicking a line should take you to the line or context of the result.

while we're at it, can i use javascript syntax highlighters when implementing this task, or would you like to stick to the current highlighting option? (pygments).

It would be nice to have an option, but I think the JavaScript way would be better in the end. As long as it supports jumping to a line number and highlighting. Essentially supports the features that are available now. The results also need line numbers. So I would say make a new branch for the JS highlighter.
