Fixing a few small things on Windows. * No os.environ['USER']. * get_home_dir() now first looks at %HOMESHARE% to get a UNC shared path if it exists. * Minor fixes for setupbase.py.

More work on the kernel.

Added .pid files to ipcluster and ipcontroller and daemon mode. * The ClusterDir object now creates a /pid sub-dir for storing .pid files. * Both ipcluster and ipcontroller now create .pid files upon starting. * Both ipcluster and ipcontroller check for the existance of .pid files before starting and won't start if another instance is running. * ipcluster has a daemon mode (--daemon/--nodaemon) will daemonize the process and then write the .pid file. * Added a "ipcluster stop" subcommand which looks for a .pid file and kills the process.

Parallel magics (%result, %px, %autopx) are fixed. * They are now a proper extension using Components and the extension API. * The are loaded by the cluster profile.

Work on updating parallel magic.

Work on default config files and docstrings. * Updated and documentated all the default config files. * Updated docstrings in launcher.py and clientconnector.py.

Work on engine/client reconnect logic.

Changed the INT then KILL delay to 2 s to be a little more friendly.

Added a log retrieval interface to Cluster.

Most of the new ipcluster is now working, including a nice client.
