Fix bug in FractalADLLobManager : create log output directory only when the first log message is written (So do not create it if no log message is written in log file).

fix bugs on code generation in juliac-core, add method UnifiedClass.getInstanceMethods() (name of the method should be reconsidered) who permits to get all public methods usable by the calling UnifiedClass (should be implemented for UCtClass), and add UnifiedMethod.getDeclaringClass() who permits to get the UnifiedClass who is responsible for UnifiedMethod.

fix bug on code generation of generic services, more tests will have to be realized later with generic exceptions...

For example: new NodeKind("software-unit", "component", [su-properties]) defines a new node kind called "software-unit" that inherits of the properties of the node kind "component".

No longer assume OO is the optimization level when none is specified. The ADL parser (such as in the case of ultra-merge), may play this role.
ULTRA_MERGE is now an ADL parser instead of an optimization level.

Enable InterceptorClassGenerators with 0 source code generator.
Rename TestableInterceptorClassGenerator: the Testable prefix seems to get JUnit into trouble.
Improved error message in Console.

New method in Console.

Rename the InterceptorSourceCodeGenerator interface to InterceptorSourceCodeGeneratorItf to unify the naming convention (Itf suffix for interfaces.)

In juliac-core upgrade the tests with the lattest version of the Console class which was implemented for juliac-tests-tools.

Done for OW2 FraSCAti.

Some improvements contributed by Bastien Sauvan (better flexibility to extend the model, more explicit exceptions).

Use regexps to capture location info from node source. Add static methods to generate node source String with the correct format 

Refactor by merging ITBasedClassGenerator and ProxyClassGenerator into ProxyClassGeneratorItf. Rationale: ProxyClassGenerator was the only subtype of ITBasedClassGenerator and had no other subtype or implementation. The separation was not making really sense.
