Add a MeanDepthItem that has 2 strings.

Dirk's implementation of the MeanDepth item was correct, but in order to
add the 2 strings to it ( one at the begin, one at the end ) I had to put
more stuff inside the ProfileWidget that's already packed with graphics
items.

So I created a new class MeanDepthItem that contains these 2 strings and
will get updated whenever the value changes.

I also fixed a math inconsistency where I changed RIGHT to LEFT.
(wich fixed a few text-placements, and broke others.)
