2.3.1

Improvements

• Added a new word function for linear change over time:
  "time from 50k to 100k at 5k every week" (= 10 weeks)
• Special logic to handle the "TOP" currency so it doesn't interfere with natural language uses of the word "top"

Bug fixes

• Fixed an issue where lowercase timezone abbreviations were not respecting the preferActiveTimeZoneAbbreviations flag
• Corrected the coordinates for 4 UK based cities
