Dialog styles moved from basic.style to dialogs.style.

Many minor design improvements in the new profiles.
New drafts design in the dialogs list: no icon, red badge.
Verified checkbox added to the new profile implementation.
Drafts saving to cloud is delayed for 1 second when switching chats.
Before quitting the app makes an attempt to save drafts (timeout 1.5s).
