Updates master to version v1.0

... and not all devices. For this functionality, the EV3-method
resetAllDeviceValues has been added.

They are now completely independent on the actual sensor type/mode handled.
If a new, unknown sensor shall be added, its type and modes now only
need to be specified in the corresponding enumerations and nowhere else.
This somehow solves issue #43.

The MATLAB sphinx extension crashes when it encounters the following
MATLAB code: "methods (Access = {?Sensor, ?Motor})" It seems its
parser does not know member access lists... I will probably rewrite
entire process.py-script soon, so the hacky and ugly workaround I
implemented is only temporary.

... that leads to bazillion error messages when there is an unexpected
connection error.

The EV3-object now handles the connection and sends commands via the
commInterface. This eliminates A LOT of redundant code (as Motor and
Sensor now only need a handle to the EV3-object, not connect/disconnect
functionality any more) and facilitates error handling.

Adapted (and cleaned up) error messages and warnings accordingly.
