GCC 4.7 Template Use Fix

This fixes our use of templates for BlockParam/ UOrbSub/UOrbPub.

Before the templates were linking only in one module and being thrown away in the rest. This made it impossible to use templates unless they were only used once, such as the current att_pos_ekf_estimator. Also this fixed the explicit typing of BlockParamInt/ BlockParamFloat (which was being used in multiple modules).

also:
* UOrbSublication/UOrbPublication were moved to the uORB module, now uORB::Publication/ Subscription
* List.hpp was moved from controllib to src/include/containers
