Remove the plotText function, standardize with the TextItem.

Browse source 
Removed the plotText function and replaced it with the
DiveTextItem class - this way there's just one way to add
text on screen, and it also makes it easy to fix positioning
of stuff there. Which is what I'll try to fix on the next commit.
