Currently the build without implicitly included precompiled header
is not supported anyway (because Qt MOC source files do not include
stdafx.h, they include plain headers).
So when we decide to support building without implicitly included
precompiled headers we'll have to fix all the headers anyway.
Now base::lambda can be copied and can wrap any immutable lambda.
For mutable lambdas there is base::lambda_once (which you're
supposed to call only once to pass data through lambda captures,
for example by using std::unique_ptr). Generally base::lambda is
passed by value and base::lambda_once is passed by rvalue reference.
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).
