Discarding a visit

The user needs the option to discard a started visit and return the app to the state just before starting theat visit. That said we need to remove all the transactional data created and revert any changes to visit and tradersite.

Even though the above statement is true, due to difficaulties related to reverting the trader site photo we do not revert any changes to tradersite photo.
