51064f5e75 Fix client initial flags setting. 
Before the server has assigned the id, the client doesn't generate flags
update messages.  This behavior is correct, but the client must then send
the appropriate flags update message when the id is finally assigned by
the server.

424bf51a7b Implement local notification. 
The default behavior is to only notify remote changes, but for some
applications (e.g. GUI's) it's advantageous to know about local
changes as well.

This is (slightly) optimized in that local changes only result in
additional resources being consumed if (any) local listeners have been
created.

6d8e796932 Disable logging on static instance destruction. 
This avoids possible deadlocks on exit when a logger callback exists.

b488cdd6ff Support immediate notify of connection listener. 
Also only perform immediate notification to the callback actually
requesting the notification, not all existing callbacks.

Offset returned uids by 1 so uid=0 can be used to indicate immediate
notification.

4146db6fc8 Visual Studio 2013 compilation fixes. 
- Missing header file callouts in some cases (library deltas)
- Lack of support for auto parameters in lambdas
- Defining of ERROR by windows.h
- Dispatcher::Connection needs a move constructor (default not generated)
- Need explicit enable_if on std::string move template in Value to avoid trying to move const char[] (string literal)
- Compile flags

e9073a3cc0 Implement notifiers. 
The notifier thread is lazily started when the first notifier is added.
This avoids the extra thread/processing overhead when notifiers are not used.

a0d30ffef1 Storage: Use StringMap instead of ConcurrentQueue for updates. 
Updates are merged or themselves updated as user code changes.  This avoids
the need for the dispatcher to do this and also avoids the need for disabling
updates when the dispatcher isn't running, because there's no risk of memory
usage piling up.

fb1b82e239 StorageEntry: Also store copy of name here. 
This wastes a bit of space but is necessary for assign message generation.

18659257d3 Storage: Make setters globally atomic. 
Previously, setters were locally but not globally atomic because they
used GetEntry() (globally atomic) in conjunction with locally atomic
gets/sets to the StorageEntry.  To support synchronizing network handshakes
they need to be globally atomic.

GetEntry() has been removed due to this issue, so a helper was added to
StorageTest instead.

5df62ac172 Storage: Disable use of update queue by default. 
This ensures we don't "leak" memory for local use when the dispatch thread
is not running.
