Complete elimination of the references to 'self.relax.data'.

All of relax now handles the singleton design pattern of the relax data storage object, referencing
the global 'relax_data_store' which is set to the reference of the single Data() instance.

major overhaul, explicit running of individual tests now work

Updated many modules to use the new singleton pattern of the 'data.Data' class.

Added an import statement to the 'data/__init__.py' file to simplify the module.

The class Data() can now be accessed by typing 'from data import Data' rather than
'from data.main import Data'. This will simplify the usage of this module for the data model
redesign and allow file names in 'data/' to be changed without affecting the operation of the rest
of relax.

Converted the Data() class from the 'data' directory into a singleton.

For more infomation about this usage of the singleton design pattern, see my post at
https://mail.gna.org/public/relax-devel/2007-03/msg00012.html (Message-id:
<7f080ed10703070006s309a1e1do38e621f48d8f6d9e@...>).

Created the infrastructure for the splitting up of the 'specific_fns.model_free' module.

The directory 'specific_fns/model_free/' has been created and the file 'model_free.py' has been
moved into it. To retain the same 'specific_fns.model_free' module namespace, the '__init__.py'
file of the new directory uses import statements.

Fixed a spelling mistake in the command line argument help system.

Added the svn:executable property to the unit test runner.
