Changes websetup.py file to correctly setup testing environment:
  1. SQLAlchemy points to test database named: test_abstrackr
  2. If test.ini is used during websetup.py call then drop
     database first before continuing to build tables
Adds functional folder in abstrackr/tests and puts in __init__.py
file. Without this file, nosetests will ignore any test packages
within it.
Adds logging parameters in test.ini and removes the reference to
development.ini (to prevent overwriting the production database
tables.
