Remove dead code

[Vincent]

I see 2 ways to rise the unit test coverage of our projects:

1. Write more unit tests.

2. Remove code.

I think that removing unused ("dead") code is a great way to improve the software quality of Synergy. It would make the code base more understandable and would also make the unit test coverage rise (since there would be less code without unit tests).

Here is an example of removing dead code from synergy/common: https://github.com/indigo-dc/synergy-service/pull/14.

Looking forward to your opinion on this.
