Add -Werror flag to compiler.

[Issue#]   N/A
[Problem]  Compilation warnings being ignored by developers
[Cause]    Too much compiler output
[Solution] Adding a -Werror compilation flag so that warnings are
           treated as errors
[Verify]   Check that the project builds without warnings

Compilation warnings should not be ignored. They often warn about
things that may cause trouble if unattended. Too much warnings also pollutes the
compiler output making it illegible.
Adding this compilation flag will allow us to maintain the quality
of our code.
