AO3: Get Current Chapter Word Count

Userscript to count the number of words in the currently viewed chapter and display them in the work's statistics area.

Credits to:

• The OTW for making the AO3 source code open source, which let me look at how they count words in a chapter.
• Will's answer on StackOverflow for a way to mimic the .scan method in Ruby.

This userscript has not been tested on non-English works. If you encounter any errors please let me know.
