New print options added!

The army builder now supports four different formats to print in. The "classic" mixed list, a list without grids, only the grids and both the previous options. I also added an option to add some extra text to your print.

This was the option which won the feature poll by the way. Next up are the tiered lists for the retribution. It is really hard to get it working for all browsers on all operating systems, so if you have any problems, please let me know.
