fixes this bug

An anonymous namespace sneaked in while porting the ocl header to the RTT
namespace.

This patch fixes it, I've also pushed the fix to the toolchain-2.3 branch.

testcase for Bug #840

All source files include the new rtt/Component.hpp header file. I attached a
simple test case with two components that are compiled in a single library.
This example fails with the same error on my Ubuntu system.

The bug is that one of your files includes rtt/Component.hpp and the other
ocl/Component.hpp.

We're thinking of a solution to fix this. Probably the most easy/reliable one
is to let ocl/Component.hpp include rtt/Component.hpp
