Ben Batt 433f6c7043 Integration of the Google Summer of Code Modifier Stack Upgrade project. The 
main features are:
* Modifiers can now be in any order in the modifier stack
* DerivedMesh now has a standard framework for custom element data to be passed
  through the stack with mesh data (being copied and interpolated as
  appropriate), so modifiers can access whatever data they need
* The modifier stack code has been refactored and a number of bugs have been
  removed
* The EdgeSplit modifier has been added:
  http://mediawiki.blender.org/index.php/BlenderDev/EdgeSplitModifier
* The DerivedMesh modifier has been added:
  http://mediawiki.blender.org/index.php/BlenderDev/DisplaceModifier
* The UVProject modifier has been added:
  http://mediawiki.blender.org/index.php/BlenderDev/UVProjectModifier

For more info, see:
