- Sort the ChanMsgItems of the channel by date

ChanMsgItem:
- Fixed adding all files (SubFileItem) again by pressing the unsubscribe button (only in Friend Storm)
- Enable unsubscribe button only when channel is subscribed (only in Friend Storm)
- Fixed adding files with umlauts (utf8) on Windows
- Enabled Download and Play button in ChanMsgItem, when they are enabled in the SubFileItems
