Fixed two things:
1. font.face.descent was a negative number. To get the full font
height, the absolute value of it needed to be added.
2. Was printing the footer to the middle of the space left between the
bottom of the cards and the margin. For small spaces this gives up 1/2
the room. So instead, printing the footer at the very bottom of the
margin.
Added the option to start the alternating tabs with a left tab, or a
right tab.
Clean up of help text. Fixed one case where overlapping options did not
make sense.
Consolidated options on tab location and tab text alignment. Options
that were generally mutually exclusive to each other were combined.
Replaced --center_name and --edge_align_name with single
--tab_name_align that takes the parameters left, right, center, centre,
edge (default=left)
Replaced --samesidelables and --fulltab with --tab_side that takes the
parameters left, right, alternate, full (default=alternate)
Added 3 enhancements:
--fulltab to make the tab the full width of the divider
--center_name to center the card name on the tab
--back_offset_height to add points in the vertical direction on the back
page
