correction for Liquibase Quick-Start

The example on http://www.liquibase.org/quickstart had defaultValueBoolean=“1”. With MySQL, this made a column like so:

      Field: active   Type: tinyint(1)   Null: YES     Key: Default: 0   Extra:

To make it work as intended (ie: Default: 1) I had to use defaultValueBoolean=“true” instead. I updated the wiki page thusly.

Thanks for catching that, you changed it to the correct value.  Feel free to fix up or improve any other documentation problems you find as well.
