Moved the Spring config files into the src/main/resources folder so the integration tests can find them.
Added a new spring context config file spring-common.xml and refactored a little bit of the context config into it. Provides better re-use for the integration tests.
Wrote integration tests for PriceDaoImpl and SupermarketServiceImpl. Renamed PriceServiceTest to PriceServiceTestImpl.
Wrote integration tests for SupermarketService and BasketParsingService. Added transaction manager support to the tests. Un-did some class renames.
