Corrected mistakes in English.

Corrected mistakes in English.

Corrected the way the scaling matrix is assembled.

This is as proposed by Ed in a post at:
https://mail.gna.org/public/relax-devel/2009-01/msg00079.html

The scaling values are now based on the default values for the different parameters which were
slightly modified.

The only parameter for which the average is still used (as for intensities in the 'relax_fit.py'
code) is 'R2eff'.

The "'" character is stripped so __det_pdb_element() better handles RNA.

Added 'SG' to the translation table.

Shifted __det_pdb_element() to the correct location.

Added an amino acid translation table for determining elements from PDB atom names.

The internal PDB reader now has rudimentary support for element determination if that column is missing.

Bug fixes for the non-protein and non-RNA Scientific python molecules.

A new MolContainer list-type class has been added to store the molecules.

Bug fix for the load_pdb() method.

Molecules other than proteins and RNA are now correctly stored and their type set in mol_type.
