Fix (hopefully) another threadign bug, reported by Jorgen.

Only use alignment specification if it's the first yielded result. Reuse ipipe.xformat() in ibrowse.ibrowse.getrow().

Fix win32 line endings.

Fix alignment default.

Make left alignment and full output the default and remove yield (-1, True) where possible.

Move textwrap import to where it's needed. Change Fields to ipipe.Fields, as ibrowse now lives in its own module.

Add missing import.

Use IPython's user namespace for the global namespace in ifilter, ieval and isort.

Copy over docstrings from the path.path methods.

Rename ipipe._default to ipipe.noitem (which makes the object public and better describes its use).
