Make iptest more reliable under Win32. This ensures the trial part of the tests runs in win32.

Add searching of .py files to find_cmd so Twisted's trial runner is found. Fix necessary for the test suite to run under win32.

Small fixes to get a cleaner doc build, and junk removal. Cleaned miscellaneous warnings raised by the doc build by fixing little reST compliance issues, and removed the testing/attic directory which was unused by now.

Remove empty doc build directory.

[merge] Merging with upstream trunk.

Add %paste to automatically paste clipboard contents. Function contributed by Robert Kern, thanks! Original code mostly unmodified, but I added 4 actual tests with a mock clipboard function so at least the core functionality can be auto-tested, even if we can't test real clipboards across platforms.

[bug] Close debian bugs: remove debian/ dir and add missing man pages. This closes the bugs: https://bugs.launchpad.net/ipython/+bug/291143 https://bugs.launchpad.net/ipython/+bug/368719 The manpages were contributed by Debian's Stephan Peijnik, and lightly edited to update them with current trunk functionality.

Remove unmaintained ipykit, as per discussion on list.

[merge] Merging with upstream trunk.

Merging (slightly modified) Tom Fetherston's demo branch. I made some small cleanups and fixed a few conflicts, the bulk of the code is Tom's. Many thanks for this contribution!
