Remove code associated with history field in the database entries.

These are no longer functional and thus superfluous.
Display library labels since database files are sometimes missing names.

Using the filename rather than the user-set name in the database file (which
is sometimes missing) is safer.
Load all depositories when loading kinetics database.
Switching thermoSearch to point to views.moleculeSearch
More changes for the transport data display module.

Added necessary urls and views. Transport database
hyperlinks now show up on database page. Displays
transport libraries and groups.  Added additional button
for searching transport on the Molecule Search Form.

Currently incomplete as transport entries for individual
molecules cannot be displayed yet.
Added Transport Search and molecule hyperlinks.

Can now display transport molecule diagrams and properties
via clicking on individual molecules. Can estimate 
transport properties via Transport Search.
