bug: imports added to generated sources are never used

[pvojtechovsky]

Test case:

• The Spoon pattern is based on java source which imports template class like e.g. com.somepackage.Request
• The Spoon pattern replaces this template class by another class, so the com.somepackage.Request isn't used in generated code.

bug: printed sources contains import of com.somepackage.Request if any javadoc contains substring "Request".
I my case the javadoc was, which caused that is: Generated by com.somepackage_generator.templates.soap.RequestBuilderTemplate#serviceWrapper(RequestBuilderTemplate.java:25)

The problem is in /spoon-core/src/main/java/spoon/reflect/visitor/ImportScannerImpl.java method visitCtJavaDoc
in code
javadoc.contains(ctImport.getReference().getSimpleName())

Spoon should understand javadoc better before it marks import as used.
