I2C support

I2CDevice is introduced to implement devices driven by I2C protocol.

As example accelerometer sensor ADXL345 is implemented.
Look at #connect and #readCoordinates methods for details.

In short: i2c device provides i2cConnection variable which should be used by concrete device class to read/write required data from physical device.
The instance of i2c connection is obtained from board using:

board connectToI2CDevice: 16r53 "address of ADXL345"

Based on new TelePharo and Calypso

Baseline references latest TelePharo version 0.2

PotRemoteBoard update remote pin instances on local write operations

PotRemoteBoard update remote pin instances on local write operations.
It fix problem when local pin and remote pin were desynchronazed

Connecting now restores all pins state

board improved connect/disconnect protocol.
Connecting now restores all pins state.
