title: Getting "Invalid default value" when upgrading Liquibase from 3.2 to 3.3
body: <p>I was using LIquibase 3.2 and am trying to upgrade to 3.3 and I'm using MySql 5.5.  However, upgrading is failing for the following types of change sets ...</p>
  
  <pre><code>&lt;changeSet author="me" id="my_changeset"&gt;
      &lt;addColumn tableName="my_table"&gt;
          &lt;column name="STUFF_VISIBLE" type="BOOLEAN" defaultValueNumeric="0"&gt;
              &lt;constraints nullable="false"/&gt;
          &lt;/column&gt;
      &lt;/addColumn&gt;
  &lt;/changeSet&gt;
  </code></pre>
  
  <p>It fails with the error</p>
  
  <pre><code>Error: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Invalid default value for 'STUFF_VISIBLE'
  </code></pre>
  
  <p>IS there any way to fix things without having to readjust all the checksums?  There are a number of occurrences of these types of statements in my Liquibase change sets.</p>
