Lots of refactoring of the helper script.. 
 * Much more flexible about what dir you are in when creating modules/actions/views/models
 * Erradicated 're-using' dir variables for different directories
 * Added two new phing tasks
   * AgaviFixPathsTask - makes an attempt to determine the real project path and sets project, webapp, and tests dir vars accordingly
	 * AgaviListModulesTask - creates a list of modules in the project
 * references #48, I'd close it but I want to get some feed back from windows people first.
added WEBAPP_NAME setting to hold name of the project closes #39
Set a default if calling agavi action from inside a module's dir or subdirs.
Fixing 6145b5476b62f5d5a81ecc384f9789b6e8485847 - adding declaration to code template settings.ini, too, and replace tabs with spaces
Fixing typo in sample autoload.ini. This closes #50.
Fixed extractParameters to return a null value for non-existent parameters, added a more complete suite of tests for the request object, and fixed up the doc block.
removed superfulous ampersands from the assignments
