Berthold Stoeger 176a62f752 profile: improve calculation of the right border
The time axis might need some space and the average depth item
puts a formatted depth at to right of the profile. Consider
these when calculating the right border.

Since I found no way to turn of the average depth, this creates
a permanent border, which might or might not be a good thing.

Contains some refactoring of the label-size functions provided
by DiveTextItem.
