Improved Y axis with Yopero's suggestion.

Z carriage shows the name of the machine, using orbitron.dxf font from Write.scad.
Updated templates and renders.
Updated README to show changes.

+**Hardware:**  
+* v0.9.6 has a robust Y axis motor stand (improvement suggested and tested by Yopero), and the Z carriage now shows the name of the machine (how cool is that? :P)
+**Software:**  
 * First Z probing results are promising, read: https://plus.google.com/u/0/113437723819360223498/posts/9VCHqqnirj6  and https://plus.google.com/u/0/113437723819360223498/posts/89W2cv1fgQW  
 * Added the python probing script (v0.1) and Octave/Matlab visualizer  
+**Firmware:**  
+* No news, it is Marlin with support for G30 probing command

 - Z axis concepts by **Quim Borras** and the spindle motor holder by **Misan** were really useful!! Also, **Diego Viejo**'s machine was of great inspiration for the Z axis (https://plus.google.com/u/0/photos/113930344830086538817/albums/5868944432651911713?authkey=CLDJgdehlN773gE) **Thank you all!!**
