The list-type data can also be a numpy array, so the Monte Carlo code can now handle this.

Previously the data was being converted from an ndarray to a list, but now this is explicitly
handled.

The NOE specific analysis now uses the dictionary type structure for the intensity data structures.

Fix for the API base method _return_value_general() - not all values have errors associated with them.

Redesigned the specific API common method _return_value_general() to handle dictionaries.

Improved execution locking with support for auto analysis and script launching from within a script.

The 'scons clean' target now removes temporary relax save files.

Fixes for the system tests - the data is now in dictionaries.

Fixed issue with incomplete data as for NOE calculation (see http://svn.gna.org/viewcvs/relax?rev=11845&view=rev
).

If data is missing, error is not displayed in wx.MessageBox, as it crashes teh GUI, but is listed in controller.
