There are some places in Peer Review don't support I18N yet, details can be seen in the attachment before*.png.
1. Title of 'Sample Peer Evaluation'
2. 'Title' of new Sample Peer Evaluation
3. 'Category-1' of Create a new rubic
1 & 2 can be solved by adding new properties.
3 can be solved by moving 'Category' to <th> tag and remove the 'Category-1' from js file.
After the modification, we can get Lesson Builder fully I18N supported.
