Title: Add support for a boolean type, better error reporting

Hello,

This pull request contains two enhancements:
- Addition of a boolean column type. It stores the value in Dynamo as either the string 't' or the string 'f' but converts to/from Ruby's constants
- A little nicer error reporting, specifically, it raises ArgumentError when you specify an unsupported column type rather than silently writing nil to the column
