Allow family drop down to show all families

This is easier than having to scroll or anything like that. This was suggested
by Dr. Zirbel.
Add a move fragments script

We need to move and rename the pdb fragments that we display. This script
handles that. We add a case flag to indicate if the fragment is cWW, cwW or cWw
since we cannot rely upon case on all servers.
Add a url data entry
Add pdb file fragments to display

We use prealigned fragments for display now. This makes the superimposing
problem not an issue. This commit adds most, but not all of the fragments we
wish to display. Notably, we do not have fragments for things like: cWW and cwW,
only cWw. The filenames do not use case to determine if it is WW, wW or Ww.
Instead we use a flag of 0, 1 or 2 to show this.
Use new data

Dr. Zirbel has provided some new data. This data includes new images for the
base pairs, pdb fragments, improved counts and better exemplars. I am now using
all this data in the updated catalog. The fragments are provided for all pairs,
meaning we no longer need the warning symbols for missing pairs. This is what I
will remove next.
Remove warning symbols

There is no need to use warning symbols in the new setup, we have 3D structures
for all things.
