• Chatbox now supports predefined nick and option to disable nick.
• Collapsable right column
• Close icon in chat tab

Improvements, Bugfixes

• Few PHP calls were not compiled. So a little bit more performance gain.
• Seems if user disabled chat sound, he could not start chat next time. Not sure still.
• Various other small improvements.

No database update this time. Demo also was updated.
