Bug 25597: Add missing Javascript libraries to sco printslip

This patch adds missing Javascript libraries to the self-checkout
print slip. These missing libraries were preventing the auto print
prompt and close. There was also a font error.

To Test:
0) Apply patch
1) Turn on system preference SelfCheckReceiptPrompt
2) Check out item via /cgi-bin/koha/sco/sco-main.pl
3) Click "Finish"
4) Press F12 on keyboard and choose Console
5) Note no Javascript errors
6) Note that print dialog appears and closes after
a print option is chosen
