When functions need to run within transaction they will create a new one, but avoid nesting transactions (see with-txn macro)

introduced classes db-ext-env, db-ext and ext-cursor which store buffer reader and writer functions in its instances, thus user only needs to work with objects

fixed some bugs preventing secondary databases to work when db-txn is used as database representation

introduced new classes to handle database depending on environment they are opened in, modified methods to handle new classes and added secondary database support depending on database type (which is specified by db-open depending on the environment)

methods using transactions don't rely on using class txn, thus nil instead of using a transaction is valid

forgot to update some functions when updating db, cursor, txn and db-env to classes to handle these classes... update now...
