Fix highlighting 10325

Fix for: #10325
Also discussed here : https://groups.google.com/forum/#!topic/brackets-dev/SPokrvCyh9Y

The goal of my fix is to add (actually keep) a highlight on the (now) inactive-pane focused line when you use several panes and have the "Highlight Active Line" option checked.

Here is how it looks like with the light theme :

With the dark theme :

Only the currently focused line has a line number colored differently to clearly see the difference between active and inactive pane. (and the highlight is a bit dimmer for the inactive pane)

As it is just about styles, I didn't modify any JavaScript, I only modified LESS files.
I tested that the modification was effective both on light and dark theme, for normal and inline editors.

@aringot For inactive pane in general line number appears highlighted. But for Nested inactive pane, line numbers have no highlight. Was this intentional?

Sorry guys, I've been pretty busy...
@prksingh , given my commit messages I got highlight even in the Nested editor. I'll try to have a look at it but I changed my laptop and OS, so I'll need to set everything up again.
