Add new testclass: MainTestSettingsFrameUsingSpringAndDb

Then we have one test using Spring and db and the other not
New class PictureIdAndHashtags

PictureController might need this to update the hash_pics table
Syso in ViewController while testing random and displayTime
Modified PictureController heavily

PictureController will now save only new pictureData to db instead of
both new and existing. We also need to find a way to add new hashtags to
existing pictureData. Use getNewPictureData instead of searchPictureData
and processPictureData for service. This modification is not completed
yet...
PictureControllerTest adjusted to changes in PictureController
