Reduce plugin dependencies of Spray diagram plugin

[GoogleCodeExporter]

The code produced by the Shapes and Styles generator produces classes that 
implement framework interfaces/classes that are part of the DSL plugins. This 
currently means that the produced diagram plugin must have a dependency on the 
Shape/Style DSL plugins themselve.

The produced code must be independent of the language implementation. For 
runtime framework classes the o.e.s.runtime.* plugins are there. 

These framework classes must be moved to org.eclipselabs.spray.runtime.graphiti:
- ISprayStyle
- DefaultSprayStyle
- ISprayShape
- DefaultSprayShape

Code generator templates must be adjusted.

Need also to move these classes:
- ISprayConnection
- DefaultSprayConnection
- ISprayShapeConstants
- SprayLayoutManager

Changed generator templates:
- StyleGenerator
- GeneratorShapeDefinition
- GeneratorConnectionDefinition

Changed project wizard to not include the DSL plugins in the manifest of newly 
generated projects. (SprayProjectCreator)

Further figured out that a dependency to org.eclipse.xtext.ui only exists 
because we need 1 class from it. Copied 
AbstractGuiceAwareExecutableExtensionFactory and removed dependency.

Dependency to org.eclipse.xtext.ui is also needed for other purposes (e.g. 
IURIEditorOpener), need to leave the dependency.

Consolidated constants from ISprayShapeConstants into ISprayConstants. One 
interface is enough.
