BUGFIX:  This change fixes #2475, where contour labels added manually
produce ugly spikes in the contours.  The problem was that screen
coordinates were being passed as data coordinates when the contour was
split to add room for the label.

Incorporate my fix and miili's #2806 change

BUG/API : tweaked how AnchoredSizeBar handles font properties

 - removed the explicit `prop` from
    `mpl_toolkits.axes_grid1.anchored_artists.AnchoredSizeBar`

 - if `prop` is not None and `fontproperties` is None, then use
   `prop` in place of `fontproperties`.

BUG : fix errors when using fliers

doplot for horizontal boxes (internal bxp helper function) assumes that
it will be passed an even number of positional arguments which it swaps
pair-wise.  The code to draw the fliers also passes in a format string
which breaks the assumption.

 - re-worked how `bxp` deals with the `sym` input
 - minor pep8
