+ ADD amount field for weapons as to make adding explosives etc. more comfortable
+ DO NOT FIX internet explorer not being able to download the statcard. Use the print button or another browser instead. (See spoiler)
+ CHANGE font size a little smaller on backside so that larger creations with the attribute table fit on it.
Nothing against IE, I actually tried to get it working for 2 hours but it was not possible. The problem is that IE does not support linking directly to data URLs in general (which all other browsers do) for security concerns for certain data URLs. A (really bad but the only) workaround is to make the browser generate the image, then send the image to the webserver, let a PHP script on the webserver generate an image IE would accept and send it back. 1MB of transfer later, IE presents the user the image. However, thats not the end of it. There is a bug in IE that prevents the user to "Save as..." the image. It claims the image displayed does not exist (or that saving it has been blocked).
This could theoretically be circumvented as well by sending back a response header named "Content-Disposition: attachment" along with the image that forces the browser to directly show the "Save as..." dialogue and not display it inline in the browser. This however does not work at all in IE11. Citation: "It seems that Internet Explorer has the worst track record of the Content-Disposition header support." Not sure if this is a bug since Content-Disposition is not in the standard RFC but is implemented by ~all browsers (except IE obviously) anyway.
