Removed all references to 'run' and removed some useless comments.

Updated the ancient palmer.py sample script to the new design.

Fix for the call to the fix() user function.

Removed the state loadings which was uncovering a pickling issue.

This bug is now caught by its own system test.

Created a system test for the saving, loading, saving, and loading again of the system state.

Shifted the pipe creation from setUp() to the script to allow for stand alone execution.

Bug fix for the reset() user function - the generic_fns.reset module was not properly imported.

Fix for the palmer.py sample script.

The model selection data pipe is created by the user function so it shouldn't be created beforehand.

Switched from os.spawnlp to os.popen3 for proper IO redirection.

This allows the system tests to capture Modelfree4's STDOUT and STDERR streams, as they are fused
into relax's.

Many fixes for the Modelfree4 execution system test script.
