[DONE] Tilt direction for level indicator

[Marsu42]

I really like the "always on" level indicator in the lv, but unlike the Canon original via INFO the ml version is rather small and I personally always find it hard to see to which *direction* the camera is tilted - if the tilt is very little you have to watch for the two small steps in the white line which is very awkward when not sitting in the comfort of your home...

Suggestion: Add a way to immediately see to which side the camera is tilted, I can imagine these possibilities:
* add a dot to the end of the line that points downwards or if that's too hard to code
* colorize the line differently for left/right tilt.

There is a degree indicator, look at the sign.

Wups, I missed the numerical value, it's very small and +/- is difficult to see when outside and looking from an angle at the screen, but it's better than nothing I guess.

Still, I think an additional indicator at the horizon line would be nice, but I'm marking this as [DONE] anyway since you've probably got more pressing things to do.
