Improve performance of domain model completion in Spray DSL

[GoogleCodeExporter]

To enable references to domain model elements from EMF models found in other 
workspace projects in every completion the complete workspace in scanned again.

There should be added some clever caching, e.g. only calculate EMF models when 
scoping the packages. 

Also the scope of the domain model classes should be reduced: Only classes from 
EPackages whose import is declared explicitly in the Spray DSL should be 
proposed.

When changing an existing domain model project the Scoping still uses the 
cached values instead invalidating the cache, cf.

a workaround for the cache rebuild problem is to restart Eclipse

the (re-)calculation of available and accessible EPackages is triggered if 
referenced Java projects of the current Java project are dirty (the current 
project is excluded as when the generator runs, this project is too often 
dirty).
