Sakai display site type directly to users.
This is not friendly to a university with multiple languages.

Some effort has been made to handle this problem, like SAK-12397. These issues remain unresolved.

Here is my solution.
Just like the tool menu did, it uses the tool id (sakai.profile2) or customized title stored in DB, and gives users the L10N label.
To achieve this goal, some work should be done.
1. Add a new properties file under folder config/localization.
2. Add a new method getLocalizedType() to Role to get the localized label of the role. And new method is needed in SiteService.
3. Modify the tools shows role id to show role label.

I'll create some sub-task to achieve this goal.
