Suffixes with Multiple Periods Not Detected #2

Suffixes with multiple periods in them (such as M.D.) are not being detected by parse-names.js. For example, "John Smith, M.D." is parsed with "John Smith" as the first name and "M.D." as the last name. The fix for this is to modify line 141 to ignore all periods instead of just the first period.
