Remove deprecated thermoSearch and transportSearch

Now both point to molecule search, which has additional buttons 
for searching transport and thermo.  Remove thermoSearch function 
in views.py as it is a duplicate of molecule search.
Add module for displaying solvation libraries and groups.

Currently estimation of solvation properties is not yet working, 
therefore solvation search points to a search page without
capability for searching the properties.
Some fixes to not fail on solvation and thermo entries when structure is missing.

Also fixed some docstrings and removed nonfunctional urls.
Create group drawing module that allows user to draw group using its adjlist.

Also added groupEntry pages to provide adjlist information for groups.
Statmech database display module. 

Also made groups clickable to group information pages that display adjlists.
