Filling the Wiki with documentation

[yschroeder]

We should add some documentation:

• Pinout of the different headers
• Instructions for assembly
• Information on connectors and power supply
• Available options for housing, tip rest, cables, grip, hall sensor...

This should be done in the Project Wiki.

In my opinion the following sentence on Wiki page "Special parts needed" doesn't make sense. If they aren't interchangeable why it's possible to choose?

You can buy it with different tips that are not interchangeable so make sure you order the one you think suits you best. We use the 0.2mm needle tip a lot and are very satisfied.
