Be more strict about type conversion:

* numbers are no longer auto converted to booleans, use to_boolean or != 0
  * booleans are no longer auto converted to numbers, use to_int
  * strings will soon no longer be auto converted to numbers, use to_int

Added version information ("since 0.3.7") to documentation
