Fixes for test_debugger

- Refer to correct test file for WriterThreadCase15 (as the moment
  _debugger_case14.py and _debugger_case15.py happen to have same
  contents which is why test didn't fail
- Don't manually run the tests but let the runner do it instead
Display meta data about numpy.ndarray

For numpy.ndarray, we display min, max, shape, dtype and size as first
level entries and access all internals under the __internals__ tag.

Because it can take a long time to calculate min and max, we limit such
calculation to arrays size <= 1000000 (1 million)
Merge branch 'numpy_resolver' of https://github.com/jonahkichwacoders/Pydev into jonahkichwacoders-numpy_resolver
Merged improved handling for numpy arrays.
