- premaknjeno iskanje vseh vrednosti iz Database Context v Database to Orange Table

Added context menu on treeview widget repository for categories and widgets to directly access admin console.
Reorganised context menu
Run widget with hieraricaly running all predeccessos
Reset widget
Reset workflow

- Corrected bug: when connection is removed during the process of input to parameter conversion - it was not reflected on the UI.
- Slight restyle: visibility of drop position is enhanced and move cursor is used now.

Widget configuration access link was added to the parameter dialog window (at the bottom).
User can configure his widget by:
- manually reordering inputs, outputs and parameters
- moving inputs to parameters and vice versa
Implementation required two new fields to be added in the database Input.order and Output.order

Some of the most important functionalities:
- latino dlls - compiled c# sources (not sure if this should be added at all, however it is an integral part?)
- latino python interfaces (latino.py and in library.py)
- modifications of platform: run widget recursive, parameters configuration, improved context menu, context menu icons, advanced object initializer
