Safe way to refactor the header system for core RL-Glue

[GoogleCodeExporter]

For some reason, every agent and environment that supports RL-Glue is
required to re-specify all of the agent_ or env_ methods in it's header file.

These are also defined in RLGlue.h file.  I think maybe we can move them to
some shared files:

agent_common.h
env_common.h

Both of these could include RL_common.h

Then, agents and environments still only have to include 1 file (same as
now), and they work.  Old agents still work.  BUT!  Added bonus.  We can
extern "C" the agent and environments in the common files, so any new
agents or environments that use them will be able to be dynamically loaded
through RL-Viz with no source code changes. Hooray!

I think this is done, but needs to be pushed out in a release.

I feel like this needs to be looked at to be sure.

This is done.  See here:

Have also added the appropriate macros so that the code can be included and 
linked
from C or C++.
