Added two dynamixel server implmentations: one with the FTDI and the other one with a standard serial port.
Added a new configuration file with specific information for each implementation.
Changed the examples and the configuration files accordingly.

Added a synchronization procedure in the dynamixel server to avoid problems at first power up.

Solved a problem in the read operation when there was an error on the instruction packet and the status packet was shorter than expected.

Modified the dynamixel server to be able to free the used devices when the associated CDynamixel object is destroyed.

Added a new exception to be able to detect desynchronization events.
