Enhance National Language Support on Training Materials

In the training materials of Sophos Phish Threat, there are some components not yet translated to national language (i.e. Japanese) as follows:

- Compete Quiz

- Reset Quiz

- Congratulations! You have passed this quiz achieving 100%

etc...

Most Japanese users can not handle such English instructions.

In addition, we need a clear message that indicates the end of training such as:

- You finished the training. Please close the window by click "X" button.  

We'll highly appreciate your support to enhance national language support of Phish Threat.
