Kind of solved the problem, need to test it more. Commented out the on_tabWidget_current_changed. Need to check if we need it for something

Discovered that we crash when we press multiple times loadfromDB button in GUI. It also doesn't work properly

Added support for Address. Need to do it in a better way, now it is in a simple way, need to write the whole address

added support for saving data in the database. Added cf zone index to database. Now need to fix all exceptions
