Some new colour schemes and asian language writing correction

A couple of small updates today. We have changed the header colour schemes for a few of the languages. A few of them were just a bit too bright before if you were spending a lot of time there which we hope you are!

We have also implemented proper word counting on the writing submission page for Japanese and Chinese. Please be aware that the word counting does only work once you click the Submit button. The word counter shown on the page is not accurate for Japanese or Chinese. Now, Japanese and Chinese writing will be charged the same way as for other languages - 3.33 points per word submitted.
