Merge lp:~unity-team/dee/noitcasnart-desrever into lp:dee

[Mikkel Kamstrup Erlandsen]

Make DeeTransaction insert rows in an appending manner (instead of prepending) during commit(). Several places in Unity subtly assume an appending behavior on everything. This, among others, caused results from lenses to be reversed when using a DeeTransaction.

Most of the noise in this diff is me adding tonnes of test case left and right to track this down. The real meat is in the last revision.

[Michal Hruby (mhr3)]

Who wouldn't approve 500 lines of extra tests?! ;)
