Description

This adds a new mock class for MySQLi_Result as well as modifies the existing MySQLi mocks to be compatible with phpunit (->expects() etc).
With this we can start using them in more places which makes implementing the next features easier/possible.

This depends on http://reviews.lunr.nl/r/60/ and http://reviews.lunr.nl/r/58/
