Add pid number to kernel startup message. This makes it easier to kill and restart kernels while debugging, or to find stray kernels if need be.

Merge branch 'mynewkernel' into upstream-newkernel

Added heartbeat support.

Fix small bug in UNC path context manager.

Fully refactored subprocess handling on all platforms. Now we have all process-related code in utils.process, which itself imports from platform-specific files as needed. On posix, we have reliable asynchronous delivery of stdout and stderr, and on win32 at least we have the basics that subprocess.py provides, since pexpect is not available. We also now support robust killing of subprocesses that may capture SIGINT: one SIGINT on our end is sent to the subprocess, but then we kill it, to prevent a rogue subprocess from hijacking the ipython console. Note that on posix, we now depend on pexpect, but we ship our own copy to users which we'll use if there's no system pexpect installed. UNC path handling for windows was implemented as a context manager called AvoidUNCPath.

Make our temp file mixin unittest-friendly. This does not break any nose compatibility, but it lets us use our mixin with normal unittest.TestCase objects in addition to nose-oriented tests. We're trying to lower our dependency on specifics of the nose api, so that in the future we might be able to run without nose at all (as unittest improves).

Add pexpect version 2.3 (revision 507) to IPython.external. We will only use our copy if the system-installed one isn't found. This lets us run the core of ipython on top of the stdlib, while having far better subprocess control than we otherwise would on posix. On windows, pexpect doesn't exist, so the subprocess situation is still not ideal. pexpect is MIT-licensed. For more information on pexpect: http://www.noah.org/wiki/Pexpect

Remove shell hook and system_verbose magic. This is the first step of a cleanup and rationalization of our subprocess management, so we can use a single, uniform interface for subprocess execution across our codebase.

Fix tiny typo in demo example

Fix file completion of commands with spaces in them.

Updated setupbase.py to include zmq.pylab package.

Merge branch 'newkernel' of github.com:ipython/ipython into upstream-newkernel

Minor work on the GUI support in the kernel.

Change %history to default to 'raw' history.

Fix bug where raw history had '#' prepended to every line

Numerous usability enhancements to the Qt console widget, particularly with regard to key bindings.

Fixed several bugs involving the insertion of new lines. Pressing Enter in the ConsoleWidget now works as expected.

First cut at a generic bracket matcher for Q[Plain]TextEdits.

Update messaging doc with refinements about user variables/expressions.
