1. Added --front and --back to select the type of text to display.
Options are 'card' for the card text, 'rules' for the extra rules,
'blank' to not print anything. And for --back, the option 'none' will
keep the pages with the backs from printing.
2. Added stub test cases for card text as well as tab size and text
alignment.
3. removed options --no-card-rules and --no-card-backs since they are no
longer needed.
4. Fixed issue with the tab outline drawing
