- fixed url in add_mesh_gemstones.py, the page existed 

- created pages with a gentle "to-be-written" warning where needed
  and fixed urls in:
  - add_mesh_archimedean_solids.py
  - io_mesh_stl/__init__.py

  See:

Not nice to send people to non-existing pages :)

- removed view alignment in the object creation
- added view alignment through align_matrix in the invoke

- if the 'VIEW' alignment preference is set and the object properties are changed
the object is rotated always to the view alignment of the view when the operator was called.
--> doesn't snap to new view rotation when orbiting around object and changing properties.

* Added "Truncated Cube" to Cuboctahedron descriptions/names.
* Added some wikipedia links to the comments of each geometry function.

* See also http://en.wikipedia.org/wiki/Truncated_octahedron
* ngon_fill() now supports offset bigger than 1.

* Added somne checks for input-parameters to prevent bad geometry.
* Use Vector(()) for all vertice coordinates.
* Documented some of the internal functions.
* Added invert_face_normal() to flip the normal of a face.

* Currently supported solids:
* - Truncated Tetrahedron
* - Rhombicuboctahedron
