v2.1.0

• Searches for nonexistent chapters will now return the last chapter of the respective book
  • e.g. the query "psalm 160" will yield the result "Psalm 150"
• Search queries consisting of only a single number will not return books which begin with that number
  • e.g. the query "2" will yield 2 Samuel, 2 Kings, etc.
• Added additional unit tests verifying that non-ASCII characters are interpreted properly
