Attached is a patch that adds the following to the email-ext plugin:
- Regression trigger: Applies when current build has more failures than previous
- Improvement trigger: Applies when current build has fewer failures than
- Added options to tokens:
- FAILED_TESTS: showStack option to suppress stack traces in the mail
- CHANGES_SINCE_LAST_BUILD: showDependencies option to show changes in

All of these have been tested and work on our Hudson instance.
