Patch by Jerry for issue 46:

- Unit test for sending file data from server to client.
- Removed singleton pattern from CSocketMultiplexer for easier unit testing.
- Incremented protocol version from 1.4 to 1.5 (new file chunk message).
- Storing pointer to CConfig instead of copying in CServer (so we can mock it).
- Created a common event queue for testing (timeout, quit event, etc).
- Fixed code style.
