better encapsulation of doctrine collection objects
bug fix for no values query log
first pass assign databases
subcategory-databases should be many-to-many association
database brief display
make sure each subcategory-database assign dialog is unique
create database-sequence join object
reorder and delete database sequence
make new databases and subcategories appear at the end (hacky, maybe find a better built-in way to do this in Doctrine?)
summon: make database recommendation threshold configurable
inline delete remove
on delete cascade for database sequence
database name filter
remove extra commit on migrate
