Origin/command line

Need the engine command_line pull request.

I added the command line class that reads the input from the server prompt. It has commands of list objects, print objects, and set position.
-The command line extends BaseObject and is registered in the server as a local object.
-Need to make changes in the engine to avoid that the local objects was sent to the client.
-Still have to solve the problem with #include common/matrix4.h
