*Querying webAPI for adverts content;
*Starting browsers new tab with url specified in json file
*Basic QML items and models
*Overview tab layout changes
*Storing images on harddrive (temporary solution)
*Sending queries to webAPI straight from widget (temporary solution)
coming next:
-store whole json file as url/desription need to be stored for further use
-display images of adverts from QImage, not from file stored on harddrive
-hide/show adverts button tweaking
-proper webAPI base class for querying various servers for data (prypto for instance)
