Making tests return number of failed operations when deployed.

Modified odreex::ample::test::check_all<...> to support returning the number
of failed testing operations within the check_all class template block. Added
the total<...>() function template as external access interface for the values
involved.
Tests modified to return value of their deployment call.
Added information about branches available in git.
