JecsTools - Apparel Extension

Added a new patch for allowing multiple apparel items to stack. "Apparel Extension" adds extra body part tags that are checked before a piece of apparel is determined to be unwearable. This is great for adding things such as glasses, monocles, earrings, and more.

For example, here is a ThingDef for a piece of "spectacles" apparel. This can now be worn alongside a hat, instead of taking up the hat's slot.

    <!-- Spectacles --> 
  <ThingDef ParentName="HatMakeableBase">
	<defName>Apparel_IndSpectacles</defName>
	<label>spectacles</label>
    <description>A pair of eyeglasses that make the user look slightly smarter. Can also improve vision.
<!-- Cut out lots of code -->

		  <li>Eyes</li> <!-- This is a string, not an enum, so feel free to use any custom named part. Want to make a nose-ring? Type in Nose and it can be equipped alongside this and many others. -->
		</coverage>
	  </li>
    </modExtensions>	
<!-- End of example -->
  </ThingDef>
