[BUG #6968] needed to glob some of the @ignore entries

- as @ignore doesn't do automatic globbing, not even for methods of a class
  (i.e. 'foo.Bar' and 'foo.Bar.baz' are two different @ignore items; the latter
  is not automatically subsumed by the farther)
- this might be a point of discussion
[BUG #6968] refactored @ignore parsing to be like @require etc.
[BUG #6968] make @ignore-based filtering like the #ignore filtering

- filter according to @-hints only *after* we've added the dependencies
  from qx.core.Environment calls
- make sure _analyzeClassDepsNode always has a Hint() tree to work with, even
  when called with a subtree of the class (which regularly happens during
  transitive dependencies calculation); make trans.deps.calc. much more
  consistent
