* Machining model and materials
Adds a few machinability material model
and a couple materials. There's a button in the job dialog
to assign a material.
The sanity report is updated to display the surface speed for assigned materials
* improving the machinability model
* Introduce MaterialConstant for the machinability model
This constant is required to calculate the actual specific cutting force
from the normalized value. It determines how the actaual value varies
when the actual chip thickness gets further away from the normalization
point.
* Rename some machinability properties
- SpecificCuttingForce becomes UnitCuttingForce to clearer differentiate
between normalized and actual specific cutting force. The term unit
cutting force is used less often in literature, but
NormalizedSpecificCuttingForce as property name is too long for my taste.
- MaterialConstant becomes ChipThicknessExponent, as "material constant"
is just too generic for our context. In literature, this constant is most
often just used as the symbol m_c.

Uses new material system for appearance
Each feature object now has a property called ShapeMaterial that
describes its physical properties. If it has a shape, it has a
material.
The ShapeColor attribute is replaced by a ShapeAppearance attribute.
This is a material list that describes all appearance properties, not
just diffuse color. As a list in can be used for all elements of a
shape, such as edges and faces.
A new widget is provided to allow the user to select materials in a
consistent fashion. It can also launch the material editor with its
more advanced capabilities.
