Do not plot on showEvent if dive is already plotted.

We do a force-plot on showEvent because the user can
have asked to open a dive file via command line, so
the app needs to open already with a profile plotted.

if the user opens the program, loads a map, hides
the profile by hitting ctrl + 1, then shows the
profile again by hitting ctrl + 2, we do not want
to do all the math to show the profile again, because
we already have it in memory.

this also fixes dirk's strange behavior of funky profile.
