Changes to make reset-password-dialog work on Alfresco version 4.2.x 

**Will,**
Since I'm not so familiar with the ant way of building Alfresco extensions I just tried to look through some source code to understand where to put what files. Hopefully this is correct. Please review and test it before merging. 

__This module needs to be deployed in the modules/deploy gui before it becomes functional.__

I figure you probably should put this on a separate branch (maybe I should have created the pull request from a topic branch as well...sorry in that case for not doing it...) so that the users of older Alfresco versions still can use the old version of the extension. Since I'm not familiar with how you version this stuff I did not elevate the version number, I'll leave that up to you.
