jobctrl: publish in _ip namespace after installation

Add jobctrl.py extension

- Close %timeit bug reported by Stefan.

Return ValueError catching to raw_input to (kinda) fix sys.stdin.close()i

Add nice exit/quit message to the exit functions.

- Cleanup [1786], which went in with unfinished stuff by accident. - Revert [1785] and replace it by installing our own quitter in place of the builtin (for all py versions). This obviates the need for [1785] and gives a cleaner exit. - Fix ipdb to work with python 2.5, and update ipdb color schemes with %colors. - irunner improvements, mostly for use as a doctest runner.

Apply Ville's patch, closes #87

do not crash on exit() with py2.5

Add arguments dirs and files to the ils() constructor. This makes it possible to get a list of only directories or only files.

Fix docstrings.

revert fakemodule and oinspect mods, they broke unittest. monkeypatch is back

remove OInspect monkeypatch inherit FakeModule from ModuleType (makes python 2.3 inspect.py work)

fix help() bug when running under python 2.3

Fixed the help message in the footer (which was displaying "quit" twice).

Fix typo.

Fix isort.__iter__() which was still using the mode argument.

Whitespace cleanup.

Readd ifile.defaultattrs.

* IPython/Extensions/ipipe.py: Rename XAttr to AttributeDetail and make it iterable (iterating over the attribute itself). Add two new magic strings for __xattrs__(): If the string starts with "-", the attribute will not be displayed in ibrowse's detail view (but it can still be iterated over). This makes it possible to add attributes that are large lists or generator methods to the detail view. Replace magic attribute names and _attrname() and _getattr() with "descriptors": For each type of magic attribute name there's a subclass of Descriptor: None -> SelfDescriptor(); "foo" -> AttributeDescriptor("foo"); "foo()" -> MethodDescriptor("foo"); "-foo" -> IterAttributeDescriptor("foo"); "-foo()" -> IterMethodDescriptor("foo"); foo() -> FunctionDescriptor(foo). Magic strings returned from __xattrs__() are still supported. * IPython/Extensions/ibrowse.py: If fetching the next row from the input fails in ibrowse.fetch(), the exception object is added as the last item and item fetching is canceled. This prevents ibrowse from aborting if e.g. a generator throws an exception midway through execution. * IPython/Extensions/ipipe.py: Turn ifile's properties mimetype and encoding into methods.
