Separate tools of the communications

[aitormf]

Actually, JdeRobot Tools use ICE for all, this creates many problems for us to add support for ROS.

I propose to separate communications from Tools. For this we need:

• Make internal types to be used by Tools instead of ICE. Communication lib would translate from ICE, ROS,... to this type.
• Make a Communication lib to encapsulate ICE and ROS. Using an interface that gives us the previous type, the tools do not need to diferenciate what kind of server is

This would be done interface by interface:

• laser
• motors
• cmdvel
• camera/Image
• ardroneextra
• navdata
• pose3D
• emSensor
