Release Name: 0.3

Notes:
New unit test assertions, and a serious bug corrected.


Changes:
*  A heinous bug was corrected that prevented flash.now from being correctly appended to.
* #show_flash_messages was always returning the enclosing div. Now, it will only return something if the keys contain something.
* Assertions for your unit tests. See below for details.
* Renamed middle package from flash_plugin_helper to flash_helper_plugin. This does not have any impact on your code.
