Drop local robot client copy, pull IRobotManager via YCM

[PeterBowman]

Closes #122. Notable changes:

• robotDevastation is now a YCM-enabled repo
• we'll pull roboticslab-uc3m/color-debug (not used yet) and asrob-uc3m/yarp-devices if not found on system
• bump CMake minimum required version to 3.1
• libraries and programs no longer depend on RobotLib; instead, they link to the interface target ASROB::RobotInterfaces, which propagates the include path to IRobotManager.h (now in asrob-uc3m/yarp-devices)
• delete RobotLib/YarpRobotManager, this was a copy of the RobotClient device
• the IRobotManager interface lives now in the asrob:: namespace
• the robotDevastation app now loads dynamically linked modules, that is, either the RobotClient or the FakeMotorController YARP devices (for real and fake/mock robot, respectively)
• --mock* options have been renamed to --fake* (as spoken with @jgvictores)

Note that RobotLib has not been entirely removed. Several mock interfaces, such as MockRobotManager, use their own extended API for tests.
