Fixed that nested transactions now work by letting the outer most transaction have the responsibilty of starting and rolling back the transaction. If any of the inner transactions swallow the exception raised, though, the transaction will not be rolled back. So always let the transaction bubble up even when you've dealt with local issues. Closes #231 and #340.

Added a require_association hook on const_missing that makes it possible to use any model class without requiring it first. Added that Active Record associations are now reloaded instead of cleared to work with the new const_missing hook in Active Record.

Added Base#update_attributes that'll accept a hash of attributes and save the record (returning true if it passed validation, false otherwise). Added a return value for Base#update_attribute, so that you get to know whether the save was successful or if it failed validation.
