getSignature() / getDeclarationSignature() writes method body too

All the get<Whatever>Signature methods in JavaMethod also write
method body, without {} which breaks xdoclet-2 plugins.

For example for:

public void otherDummy()

following is writen out by getCalSignature():

otherDummy()
System.out.println("other");

Quick look into sources reveals that all signature emiting methods utilize writeBody() , which
in any case emits method body.

This bug seems to be really old and was unnoticed by us because old versions did not stored method bodies at all.
