Closes #163
Closes #68

[chaneylc]

This branch improves some old code. Updates the example template and also provides an extra 3x2 template choice, and introduces a way to easily add more in-app templates in the future. A bug was fixed where male parent labels could not be printed. And also introduces various new print preferences so the user doesn't have to choose the printer every time they print.

• Add option to choose different label default in preferences (remove from the import zpl page)
• The printed cross labels have an extra string in the top left corner for me. It's underneath the cross id so I can't quite see what it is, but it looks like one of the parent IDs
• Add progress bar when printing is activated

@trife Send me a screenshot of your "ZPL Import" page so I can see your loaded template, and a picture of your printed label if you want. The current available templates should only be printing, crossid at the top, the crossid qr code in the middle, and beneath that the date:

^XA --start statement

^DFR:TEMPLATE^FS --saves template

^PW406^LH10,10^FS --label dpi and home setting

^FO0,0^A0,25,20^FN1^FS --cross id string printed in top left

^FO140,30^BQN,2,3,H,^FN2^FS --cross qr code printed underneath

^FO140,170^A0,25,20^FN5^FS --and below that the date string

^XZ --end statement,
