Renamed from class_table_inheritance to uvi
Added gemspec and rearranged lib
Fixed deprecation warning
Renamed rake task build_database to create_database
Add bundler rake tasks
Don't check for db connection adapter class

This check made sense when this lib was a Rails plugin and hence was loaded
after db connection was established. Now it's a gem and Rails loads gems
before creating db connection.
Renamed gem to updateable_views_inheritance
