Changed the alternative representation names for the frame order geometric objects.

The aim is to put both representations on a more equal footing, as they are identical solutions.
Hence the inverted representation might be the correct representation of the domain motions. So
instead of calling these 'positive' and 'negative', the 'A' and 'B' notation will be used.

This affects the names of the files produced by the frame_order.pdb_model user function as well as
the internal titles. Instead of ending the files with "*_pos.*" and ""*_neg.*", these have been
changed to "*_A.*" and ""*_B.*". The atoms used for the titles have also been renamed, and the
pymol.frame_order user function now labels the titles using the 'A' and 'B' notation.

Added titles to the frame order geometric representation PDB files from frame_order.pdb_model.

These are in the form of special Ti atoms placed 40 Angstrom away from the pivot along the z-axis of
the system, or shifted 3 more Angstrom for the Monte Carlo simulations. These are used to label the
alternative representations or the Monte Carlo simulation representations. The residue type is set
to TLE and this has been registered in the internal structural object.

The pymol.frame_order user function now calls the represent_titles() function to select these atoms,
hide them, and then add a long descriptive title. The atom name is used to distinguish between
different titles.

The tables on the http://www.nmr-relax.com/download.html webpage now have left and right margins.

Editing of the security section at http://www.nmr-relax.com/download.html#Security.

Redesigned the dependency information on the http://www.nmr-relax.com/download.html webpage.

The dependencies are now listed in a proper table rather than a HTML list, and these have all been
shifted into the dependency section. This is rather than having one section per operating system as
the dependency lists were now almost all identical anyway.

The Python packages in the Mac OS X application are now listed at http://www.nmr-relax.com/download.html.

Removed some rotation files from the CaM frame order test data directories.

These files are no longer of any use and just take up large amounts of room for nothing.

Removed all remaining uncompressed PDB files from the CaM test data directories.

These were complicating the debugging of the pymol.frame_order user function, as they were being
loaded on top of the compressed versions.

Simplified the PyMOL view commands in all of the CaM test data optimisation scripts.

The pymol.view user function is not necessary as the PyMOL GUI will be launched by the
pymol.frame_order user function. And the pymol.command user function call for running the 'hide
all' command is also now redundant.

The pymol.frame_order user function now centers and zooms on all objects.
