-> Custom Properties for Mesh entities

In order to give import/export script authors the ability to add properties
to inidividual faces, vertices and edges in the same manner as they are able
to do with ID structures three new custom data types have been added to blender
for floats, integers and strings.

Things to note:

-Since property Layers are custom data, they are added to all verts, edges 
 or faces at once.
-Only one property layer for each unique property name may exist. In  other 
 words, you cannot have a float layer as well as an integer layer
 both with the same name.
-No user interface for this exists at the moment.

The following methods and attributes have been added to the Blender.Mesh
Python module and it's object types:

->MVert/Edge/FaceSeq:
	addPropertyLayer(name, type)
	removePropertyLayer(name)
	renamePropertyLayer(original name, new name)
	properties(readonly list.)

->MVert/Edge/Face
	getProperty(name)
	setProperty(name, value)

->Mesh module
	PropertyTypes (readonly dictionary)
