Pig Salt and Pepper Shaker

I remixed the awesome Salt/Pepper Pig by Zh4x0r:
- labeled the pigs so you know which is which
- pepper pig has both nostrils open, salt pig has only 1 (this is the US way of things :-))
- put a slight angle under the pig's snout so it can print without any supports and not get stringy there
- resized the screwable tail to 95% which fit better for me
- Added the pig foot which can be printed in a flexible filament to make the foot pads rather than using the suggested sugru. I used Ninj
