[logback-dev] Connection logic moved to ConnectionRunner class

[ceki]

Hi Carl,

In the 'connectionRunner' branch (a sub-branch of 'serverSide'), I have 
modified AbstractSocketAppender to delegate most of the connection logic 
to ConnectionRunner. There are few minor differences in behavior but 
otherwise, the code is the same only DRYer. The next step is to have 
SocketReceiver to use ConnectionRunner. After that, I'll tinker with the 
SocketFactory code to allow user-specified timeout for connection 
attempts. The current timeout seems to be OS specific (1000 ms on Windows).

See the pull request [1] for more details.
