Incomplete GXT3 app wizard refactor
Integration of serialized json for displaying the wizards is still in progress, but the only pieces which remain are the application of validators, numerical and hierarchical list display.
After that, use of validators will be fully integrated, and data from the wizards will be parsed off.
Finally, the autobean data format for the new app wizards will be converted into a format which the server expects.
