+* Make style names case-insensitive in style mappings. This should make style
+  mappings easier to write, especially since Microsoft Word sometimes represents
+  style names in the UI differently from in the style definition. For instance,
+  the style displayed in Word as "Heading 1" has  a style name of "heading 1".
+  This hopefully shouldn't cause an issue for anyone, but if you were relying
+  on case-sensitivity, please do get in touch.
