Adds the unused RPK Banana Mag as a standalone custom magazine for the AK, AK 7.62, Golden AK 7.62, Krinkov and the RPK. I also updated the mag's df_cc texture so that is has basic skin support rather than just being black (see last screenshot).
The stats are identical on all weapons but the RPK. I intended for the Banana Mag to decrease the PRK's mag size to 50 but as it turns out you can only reduce the mag size by a maximum of 10 rounds. (Also, animations on the RPK will be off.)

Requires BeardLib.

Stats and inventory icon are blatantly stolen from Iron Predator's Extra Attachment Compilation.

Thanks to Dead Baron for the workaround idea.
