Chat service:

- Added send time to ChatInfo.

Chat:
- Reworked IMHistoryKeeper to save only needed data as raw data (not formatted from PeersDialog).
- Renamed the public chat history file from "his1.xml" to "chatPublic.xml" and moved it from data dir to config dir. The current history is lost. Please delete the file "his1.xml" manually.
- Optimized save of the history. Save only when changed, also during the runtime.
- Clear the history in PeersDialog clears the IMHistoryKeeper too.
- New setting to send chat message with Ctrl+Return. Changed the check for Enter in PeersDialog and PopupChatDialog from textChanged to eventFilter.
- Smileys are inserted at the current cursor position, not added at the end.
- Don't send emty messages.

New class ChatStyle:
- Created a new class for the work with chat styles and smileys.
- Currently only two internal styles are available - private and public. Later more external styles planned.
- Moved functions for loading and showing the emoticons from PeersDialog and PopupChatDialog to the new class.

Private chat:
- Split private chat style into incoming.htm and outgoing.htm.
- Removed style change.

Public chat:
- New chat style incoming.htm, outgoing.htm, hincoming.htm and houtgoing.htm.

Chat feed:
- Show links and emoticons if they are enabled for public chat.

PeersDialog:
- Show the own name and location only once at start and not with QTimer every 1.5 second.
