Part 32289b modifications and new parts

[Willy Tschager]

Proposed new structure of these motors.
I'm not sure of the red partnumbers. Since the uncoloured part is 32288, maybe the assembly should use that number as base.

I'm somewhat sceptic to this scheme as:

* 32288c01.dat - Electric Technic Motor 4.5V  6 x 17 x  5 with Dark Grey Base Type 1

is used only in one set and exclusively in Dark Grey

* 32288c02.dat - Electric Technic Motor 4.5V  6 x 17 x  5 with Light Grey Base Type 2

is used only in three sets and exclusively in Light Grey
