Attention code editor in task page may get buggy

Friends, Hi!

I've just made some "improvement" to small code-editor which you see in the bottom of each task's page - one where solution is posted.

The main change is that now certain popular languages have syntax highlight there (if you choose language with the selector above the solution area).

However there could be some bugs or the whole stuff can get broken. Please write back if you find any problem. Also note that for the first time after change pressing Ctrl-R in your browser few times may help to reload cached scripts and fix some transitional troubles.

Thank you for your patience :)
