[#BUG 7095] Table blocking mouse wheel even if empty
Tree controller now assigns node after tree is built.

This is a great way to use the changeRoot event as a trigger for things
that need to happen when the tree is available, like opening nodes.
Adds qx.Interface.classImplements and qx.Interface.objectImplements to
detect interfaces without throwing exceptions (ie they correspond to
qx.Interface.assert/assertObject), and a mod to
qx.Class.implementsInterface to use the new methods.  This patch can
greatly reduce the number of first-chance exceptions thrown by the
framework and is especially useful when debugging code which uses the
binding mechanism.

[BUG #7369] Serializer now supports serializing qooxdoo classes / mixins / interfaces to its classname.
[BUG #6968] add support for #ignore in lint checking

- old #ignore hints were not honored in the new lint implementation
- add this to be backwards compatible with the old implementation,
  so that no new warnings pop up when migrating old code to 3.0
- (was confusing anyway when a lint run would complain about the same thing
  and a compile run would not)
[BUG #5967] change tokenization of run-away delimited tokens
